摘要
软土地基承载力低,稳定性差,设计与施工中处治措施不当会导致路基沉降,破坏道路结构。在某高速公路软基处理中,采用土工格栅复合碎石垫层的处治方法,通过对处治后的路基进行沉降观测,达到了预期的效果,可以为施工一线提供一定的经验参考。
The soft foundation is with low bearing capacity and poor stability. Improper treatment measures in the design and construction will lead to subgrade settlement and destruction of road structure. During the soft foundation treatment of an expressway, the treatment method with the composite broken stone hardcore of geogrid is as to provide a certain experience reference for the main construction.
