摘要
兰渝高速铁路在陇南车站的站场工程,路基要通过松软土地基。由于松软土地基天然承载力低,采用了粉喷桩复合地基进行处理。通过现场粉喷桩单桩复合地基静载试验,确定复合地基承载力,推算复合地基复合模量,并对该种地基处理方法进行评述,为粉喷桩在松软土地区的应用积累了工程经验。
The subgrade in Longnan station of Lanzhou-Chongqing high-speed railway is constructed on loose soft soil. Due to lack of bearing capacity, The dry-cement jet mixing piles are used in the foundation treatment of loose soft soil. Through the in-situ test for single DJM pile composite foundation the static loading, the bearing capacity of the composite foundation is defined, the composite modulus is also calculated, and the foundation treatment method is discussed to provide references for similar project.
