摘　　要：软土路基在外荷载作用下,其沉降大,且持续时间长。在软土地基上修建高等级公路,潜在的工后沉降会对交通运输造成很大的危害,因此软弱地基应该采取合理有效的加固处理措施。软土地基处理的方式有很多,各有优缺点及局限性,如何选择合理的地基处理方式直接关系到工程质量、工程进度及工程投资。该文对公路软基处理方法进行了探讨、总结,可供类似工程参考。The settlement of the soft soil roadbed is large and the retaining time is long under the external load action.If the high-class highways are constructed on the soft soil subgrade,the poten-tial settlement after constructed will cause the great harm to the traffic transportation.Therefore,the reasonable and effective reinforcing treatment measures should be taken to the weak subgrade.There are many treatment methods of the soft soil subgrade.These methods have their advantages and dis-advantages as well as limitations.How to select the reasonable subgrade treatment method is directly related to the engineering quality,the engineering schedule and the engineering investment.The article approaches and sums up the highway soft subgrade treatment method able to provide the refer-ence for the similar projects.
