摘要
随着山区高速铁路建设加快,跨越山谷和河流的大跨连续梁建设得到广泛应用,高墩大跨连续梁施工越来越多,技术难度越来越大,城头清水江特大桥主墩柱高23m,主跨128m,0号块质量大,其施工难度大、工期紧,是沪昆客专重点桥梁工。系统介绍高墩连续梁0号块支架结构体系设计、支架结构验算。
The construction of long-span continuous beams across valleys and rivers has been widely used with the acceleration of high-speed railway construction in mountainous areas.The construction of high pier and long-span continuous beams is more and more,and the technical difficulty is more and more.The main pier column of Qingshui River Super Bridge in Chengtou is 23 m high,the main span is 128 m,and the weight of block 0 is large,so the construction is very difficult It is a key bridge engineering of Shanghai Kunming Passenger Dedicated Line.This paper systematically introduces the design of support structure system and the checking calculation of support structure of No.0 block of high pier continuous beam.
