选取察尔汗至格尔木高速公路路段沿线的盐渍土为研究对象，运用室内单轴压缩试验，利用单线单点法模拟现场浸水后施工特征，对该土在浸水情况下溶陷特性进行模拟试验研究。对比分析模拟试验结果与常规试验结果，发现模拟试验中土样的溶陷量较之常规试验更大，土体结构性破坏更加严重，说明在高含盐量的盐渍土地区，盐渍土浸水后会加剧路基的溶陷，为施工带来极其不利的影响。本文成果可为盐渍土地区的公路设计和施工提供有益参考。

Taking the saline soil along Qarhan-Golmud Expressway as a research object,and using the uniaxial compres-sion test and the single one-point method to simulate the characteristics of the construction after immersion,a simulation test is carried out to study the salt resolving slump in the case of immersion.Then a comparative analysis between the simulation test results and normal test results is conducted.The results show that the salt resolving slump of the soil in simulation test is more serious than that in normal test,and the soil structure is deteriorated much more seriously.It is stated that the intensified salt resolving slump will take place on the saline soil subgrade after immersion in the saline soil area with high salt content,which would bring the extremely adverse influence on the construction.The achievement of this paper could provide beneficial references for the design and construction of the highway in saline soil regions.
