摘要

用干燥法和滴水法研究了松嫩平原苏打型盐渍土在失水和吸水过程中抗剪强度参数c、φ随含水率的变化关系，提出了这两种情况下，苏打型盐渍土随含水率变化的抗剪强度公式并给出其强度参数及含水率的强度曲面，得出了不同应力水平下的临界含水率。分析了苏打型盐渍土在失水和吸水条件下抗剪强度随含水率的变化机制。其研究结果为松嫩平原地区的苏打型盐渍土工程的设计与建设提供参考。

Abstract

The relationship between shear strength and water content of Song-Nen Plain soda-saline soil is studied with two different experimental methods. A shear strength formula is brought out based on tests; and the strength parameters are given accordingly. At the same time

the yield surface and the critical water content of Song-Nen Plain soda-saline soil are proposed; and the mechanism of strength variation is analyzed. The study is valuable to the engineering design and construction in Song-Nen plain soda-saline soil.
