摘要
在公路建设的过程中,常常不可避免会通过膨胀土地区,膨胀土是公路建设中一种特殊的不良土质,一直是困扰公路建设的重大工程问题,处理不好将对路基和公路产生极大的破坏。本文首先分析了路基膨胀土的工程性质,并指出其在公路建设中的危害,进而分析了膨胀土的若干处理方法以及施工需注意的事项。
It is usually ineluctable for highway to get across expansive soil area during the constructing process. Expansive soil is a special soil with a bad nature which is perplexing highway construction,it will do great harm to highway if it＇ s not well-treated. This paper analyzed the engineering properties of expansive soil,and presented its damage to highway,then proposed improvement methods and points for attention in construction of expansive soil.
