摘要：

The P6 main pier of Zhongjianhe bridge is in the 75 degrees steep slope area, and it adopts high pile cap foundation. The site of the pier is narrow and steep, and the outer suspension of the cap is large and high, which makes the construction of the foundation very difficult. Based on scheme comparison and the steel platform method, which takes the steel pipe of pile foundation as the support member and takes the steel platform as the construction work surface of the digging hole pile and the cap pouring bottom die, is used for the first time to solve the construction difficulties of high pile cap foundation in complex mountain region. The technology has created good economic and social benefits, which can provide references for similar projects.
