Project Introduction
The Chengdu-Chongqing mid-line high-speed railway, that is, the Shanghai-Chongqing-Chengdu high-speed railway from Chongqing to Chengdu, Sichuan Province, is an important part of the "riverside channel" of the main channel of China's "eight vertical and eight horizontal" high-speed railway network. The Chengdu-Chongqing Middle Line High-speed Railway starts from Chongqing North Station, runs through Chongqing, Ziyang City, Sichuan, and Chengdu, and ends at Chengdu Station. The main line has a total length of 292 kilometers and a design speed of 350 kilometers per hour. There are 8 stations on the entire line. On November 28, 2022, the Chengdu-Chongqing mid-line high-speed rail officially started construction.
The (60 100 60)m continuous beam of the Chengdu-Chongqing mid-line high-speed railway earth bridge junction interchange double-line super-large bridge spans tongan expressway with a mileage range of DK 60 245.3 ~ DK 63 516.9. the whole bridge is located on a straight line. the hole span is 2 × 24 4 × 32 (64 1102 64) continuous beam 1 × 24 19 × 32 (60 100 60) continuous beam 11 × 32 1 × 24 47 × 32 2 × 24m, with a total length of 3271.6m. The whole bridge has 92 piers and 2 abutments. Pier 30~31, the inclined pavement width of the main road is 60m, and the intersection angle between the railway and the road is 35.29 °. The cantilever pouring method of bridge-building machine is adopted, and the calculated span is (60 100 60) m.
