The difference between Lugou Bridge and Ludian Bridge, where is Lugou Bridge?

Lugou Bridge, also known as Lugou Bridge, is about 15 kilometers southwest of Beijing, on the Yongding River in Fengtai District. Named after the crossing of the Lugou River (i.e., Yongding River), it is the oldest existing stone arch bridge in Beijing.

The Lugou Bridge is full of meters long, wide meters, and up to meters at its widest point. There are 10 bridge piers, a total of 11 bridge holes, the whole bridge body is a stone structure, the key parts are connected by silver ingots and iron tenons, it is the longest ancient stone bridge in North China. On July 7, 1937, Japanese imperialism launched a full-scale war of aggression against China here.

The Chinese garrison in Wanping City rose up to resist, and the history is known as the "Lugou Bridge Incident" (also known as the "77 Incident"). The Chinese anti-Japanese army fired the first shot of the all-out war of resistance at the Lugou Bridge.

Luding Bridge, also known as the Chain Bridge, is a masterpiece of ancient Chinese bridge construction. The Luding Bridge is located on the Dadu River in western Sichuan Province, China. Legend has it that after Emperor Kangxi unified China, in order to strengthen the cultural and economic exchanges in the Sichuan-Tibet region, he approved the construction of this bridge and set up a royal plaque at the head of the bridge.

The bridgehead castle on both sides of the Luding Bridge is an ancient wooden structure of the Han nationality, which is unique to China. The bridge was built in the 44th year of the Kangxi reign of the Qing Dynasty (1705) and completed in the 45th year of the Kangxi reign (1706). Kangxi imperial pen inscription"Luding Bridge", and set up the imperial monument at the bridgehead, the bridge is 103 meters long, 3 meters wide, 13 iron chains are fixed in the abutment on both sides of the well, 9 are the bottom chain, 4 are divided into two sides as handrails, a total of 12,164 iron rings are interlocked, and the whole bridge iron parts weigh more than 40 tons.

The bridgehead on both sides of the strait is an ancient wooden structure building, with a unique style and unique in China. Since the Qing Dynasty, this bridge has been an important passage and military point for Sichuan to enter Tibet. On May 29, 1935, the Chinese Workers' and Peasants' Red Army's Long March passed through here, and the commando team led by 22 warriors braved the enemy's bullets and bullets to crawl on the chain bridge and eliminate the bridgehead guards in one fell swoop.

In 1935, the Chinese Workers' and Peasants' Red Army "flew to capture the Luding Bridge" during the Long March, making it an important historical memorial site of the Communist Party of China. In 1961, Luding Bridge was announced by the People's Republic of China as the first batch of national key cultural relics protection units, 2 on the left and right sides, is the bridge railing, 9 side by side at the bottom, paved with wooden planks, is the bridge deck. Each chain is made of 862 to 997 interlocking wrought iron rings with a total weight of 21 tonnes.

The bottom chain is covered with wooden boards, and the handrail and the bottom chain are connected by small iron chains, so that the 13 chains are a whole. It belongs to the national key cultural relics protection unit.

Lugou Bridge is located in Yongding River, Fengtai District, Beijing, named after crossing the Lugou River (i.e., Yongding River), and is an ancient stone-built arch bridge in Beijing. The construction began in the 29th year of Zhangzong Dading of the Yuan Dynasty (1189) and ended in the third year of Ming Chang (1192). The total length of the meter, a total of 11 holes.

The bridge deck is wide, the stone carving guardrail on both sides is expected to be 140 pillars respectively, and there are 485 large and small stone lions crouching on the column head, which are vivid and lively, and the demeanor is different.

Outstanding achievements in bridge engineering

First of all, the abutment of the Lugou Bridge is built by the "insertion method", that is, piles are driven under the foundation of the bridge to increase the pressure resistance of the soft sediment riverbed and reduce the subsidence of the bridge abutment.

Secondly, in the pier structure, the water dividing tip of the pier of Lugou Bridge is specially designed, its length is about five meters, which is longer than the general ancient stone bridge, and the large stone slab with a thickness of six layers is piled up from the foot of the arch circle to press the water dividing tip. A triangular iron pillar about 26 centimeters long is installed at the head of each water dividing tip to meet the water at its acute angle.

Thirdly, among the eleven arch circles of the Lugou Bridge, the center hole is the largest, and the two sides are gradually smaller, and the ratio of increasing from the outermost hole to the center hole is 1, which is much smaller than the official practice of the Qing Dynasty (1. The arch is arc-shaped, and the sagittal span ratio is 1 strong

Lugou Bridge is located on the Yongding River in the southwest of Beijing, it is an ancient bridge famous all over the world because of the stone lion on the bridge, and it is also the largest, well-preserved, exquisite construction technology of an ancient bridge in the north of China.

The Lugou Bridge was built in 1189 and completed in 1192, with a total length of meters and a width of meters. The deck is slightly curved, with low ends and a bulge in the middle, paved with natural granite strips. The riverbed under the bridge is covered with pebbles and quartz sand several meters thick, and the entire bridge is very solid and stable on top of the masonry.

There are stone railings on both sides of the bridge, and the top of the railing is carved with stone lions, and there are stone tables at the head of the bridge. Its superb bridge building technology and exquisite stone lion carving have a unique charm, and are well-known at home and abroad.

Lugou Bridge is located in Fengtai District, Beijing.

The deck of the Lugou Bridge is slightly arc-shaped, with low ends and a bulge in the middle. The piers, arches, pillars, railings, drum stones, and Huabiao are all built of natural quartz sandstone and marble, while the bridge deck is paved with natural granite stones.

The riverbed under the Lugou Bridge is paved with pebbles and quartz sand several meters thick, and the entire bridge is very solid and stable on it. The plane of the pier is in the shape of a flat-bottomed boat, the north is the upstream, it is the water inlet surface, and the masonry divides the water tip, which is like the bow of a ship, and is long meters, accounting for about a quarter of the pier.

At the front end of each water distribution tip, a triangular cast iron is installed on each side, with a side width of 26 cm and an acute angle facing outward, to reduce the impact of torrents and ice cubes, and to protect the stability of the water distribution tip. On the top of the water dividing tip, cover six layers of water dividing stone slabs again, called Fenghuang platform, the lower two layers are picked out, and the above layers are collected one by one, high meters, which not only strengthens the stability of the water dividing tip, but also plays a balancing role in the bearing pressure of the bridge pier.

Lugou Bridge, also known as Lugou Bridge, is located in Yongding River, Fengtai District, Beijing, named after crossing the Lugou River (i.e., Yongding River), and is an ancient stone-built arch bridge in Beijing.

The south side of the pier of Lugou Bridge is smooth to the water, and the masonry is streamlined, similar to the stern of a ship, so as to disperse the water flow and reduce the pressure of the torrent on the coupon hole. The marble parapet of the bridge deck is composed of 281 pillars and 279 balustrades alternately. There are 141 lookout posts and 140 railings on the south side; There are 140 pillars on the north side, and the column plates.
