CFG桩作为软土地基加固的措施之一,近几年在铁路工程中应用越来越广泛。由于高速铁路对路基变形要求较高,而经CFG桩复合地基处理的软土路基工后沉降很小,所以,只要在施工中注意质量控制,完全可以达到高速铁路的控制沉降要求。根据CFG桩的原理,介绍了CFG桩施工过程中的质量控制方法,具有一定的实用性。
As one of the measures to reinforce soft soil foundation, CFG pile is more and more widely used in railway engineering in recent years. Because high-speed railway has high requirements on subgrade deformation and post-construction settlement of soft soil subgrade treated by CFG pile composite foundation is very small, so long as quality control is paid attention to in construction, the control settlement of high-speed railway can be fully met. According to the principle of CFG pile, the quality control method in CFG pile construction process is introduced, which has some practicality.
