摘要
随着我国高速铁路列车时速不断刷新,路基沉降控制成为了影响时速的关键,CFG桩复合地基能较好地满足沉降控制要求,但其沉降计算理论尚不完善。以京沪高速铁路济南西站为依托,对比分析了常规复合地基沉降计算方法和Boussinesq-Mindlin联合求解法在CFG桩复合地基沉降计算中的应用,并将计算结果与现场实测结果进行比较,验证了Boussinesq-Mindlin联合求解法的合理性。
As the speed of high-speed railway trains in China continuously refreshes,subgrade settlement control has become the key to affect speed.CFG pile composite foundation can well satisfy the requirements of settlement control,but its settlement calculation theory is still imperfect.This paper takes the Beijing-Shanghai high-speed railway Ji＇nan west railway station as the background and carries out comparative analysis on the application of conventional calculation method and Boussinesq-Mindlin combined method in the CFG pile composite foundation settlement calculation,then compares the calculation results to field measurement results.It verified that B-M combined method used in CFG pile composite foundation settlement calculation was reasonable.
