摘要
吸水膨胀软化,失水收缩开裂反复变化是膨胀土的特性。因此膨胀土路基的施工处理方式成为了道路工程施工的难题。从对膨胀土性质的分析入手,提出在膨胀土区域,路基施工的一些技术处理手段和防护方法,可为工程人员提供一定的参考与借鉴。
Expansion and softening due to absorbing water, repeated change of shrinkage cracking due to dehydration are the characteristics of expansive soil. Therefore, the construction treatment method of ex- pansive soil subgrade has become the problem of highway engineering construction. In this paper, based on analyzing the properties of expansive soil, some processing methods and protection methods of sub- grade construction in expansive soil zone are proposed. It can provide some reference for technicians.
