摘　　要：在公路工程中,软土路基对工程的影响十分明显,如处理不当将造成一系列的问题。以某高速公路软土路基处理为例,对真空联合堆载预压法的加固原理、施工工艺进行了介绍,并结合实际监测,对软土路基处理进行了工后效果评价。监测结果表明:采用真空联合堆载预压法处理软土地基是可行的。In road engineering,the influence of soft soil subgrade is so significant that any improper treatment may cause many troubles. This paper then,by an example of treatment of highway soft subgrade,introduced the reinforcement principle of the method combined vacuum and surcharge preloading,and its construction process,and then with actual monitoring,the construction result of treatment was evaluated. The monitoring result shows that the method combined vacuum and surcharge preloading is feasible in treatment of soft soil subgrade.
