摘要
以山西大运高速公路某段软基处置为例,通过对软基复合地基的原位测试成果分析,得出碎石桩不但提高了地基的承载力,增加了桩间土的强度,减少了地基沉降,而且消除或减轻了地基的液化,使复合地基承载力达到了设计要求,特别是为以后在高速公路修筑中的软基处理提供了参考资料。
The paper takes examples for a soft ground to handle with macadam compaction pile about Da-yun expressway in Shanxi province.It analyzes the in-situ testing result for the compound ground of a soft foundation.We can conclude that the reinforcing method by using macadam compaction pile not only improves the bearing capacity,increases the strength of the soil between piles and reduces the ground settlement,but also removes and reduces ground liquefaction.The bearing capacity of compound ground,which is handled with macadam compaction pile,achieves the designing requests.In particular,it will provide reference data for handling with soft ground in expressway construction in the future.
