摘要
为了解决膨胀土施工过程的问题,通过对膨胀的辨识,进而依据膨胀土的胀缩总率、自由膨胀率、标准吸湿含水率、塑性指数等进行等级划分,分析其性质,研究其病害。对不同等级膨胀土的路基施工关键技术进行详细介绍,同时对膨胀土路基边坡支护的施工形式以及防水系统施工过程中的一些关键控制技术进行了说明,为日后膨胀土施工提供了借鉴。
In order to solve the problems of expansive soil in construction process, expansive soil was graded according to the total expansion and contraction, free expansion rate, standard moisture content as well as plasticity index. Key technologies for construction of subgrade with differently graded expansive soil were introduced in detail. Crucial control technologies for slope supporting construction and the construction process of waterproofing system were explained, which provides reference for construction in expansive soil area.
