摘要

针对地表蒸发条件下的膨胀土开裂问题，从定性和定量两个方面进行了分析，提出了膨胀土初始开裂的基质吸力临界判据，经比较与现场实测结果基本一致。采用线弹性力学方法，研究了地表蒸发条件下的膨胀土初始开裂深度，对其与土体抗拉强度、泊松比及密度等特性参数的关系进行了详细的论述。

Abstract

The cracking behavior of expansive soil due to evaporation are analyzed qualitatively and quantitatively. The critical value of matrix suction for initial cracking is presented

which is according with results of the site test. With the linear elastic mechanics

the depth of initial cracking for expansive soil is put forward and the relations between the depth of initial cracking and soil parameters such as tensile strength

Poisson’s ratio and gravity density

are discussed in detail.
