以察尔汗盐湖地区察尔汗~格尔木高速公路沿线的盐渍土为研究对象,着重对该土在浸水情况下的溶陷特性进行了模拟试验研究,为盐渍土地区的公路设计和施工提供合理的技术指导。运用室内单轴压缩试验,利用单线法模拟出现场浸水后施工的特征,并将其试验结果与常规试验结果进行了对比分析,研究了盐渍土在浸水导致加剧溶陷后对路基施工所产生的不利影响并提出了合理的防治措施。
Taking saline soil of Chaerhan ~ Golmud expressway in Chaerhan salt lake area as the research object, this paper emphatically studied the dissolution characteristics of the soil under water immersion condition, and designed the highway design and construction in saline soil area Provide reasonable technical guidance. By using the uniaxial compression test in indoor, the single-line method was used to simulate the construction characteristics after field immersion, and the results of the tests were compared with the conventional test results. The effect of saline soil on the subgrade construction after immersed in water was studied The adverse effects and put forward a reasonable prevention and control measures.
