摘要
结合井睦高速公路工程中的山涧淤泥质土-砂混合软土，通过控制含砂量与含水率对该混合土做一系列固结压缩试验，目的是研究含砂量与含水率对该混合软土压缩性的影响．试验研究表明：淤泥质土-砂混合土的压缩模量与合砂量成正相关关系，与含水率成负相关关系；在界限含砂量区间（50％～70％）内，抗压缩性明显提高，压缩模量增大，压缩系数减小；增加含砂量，压缩系数随之减小，增加含水率，压缩系数逐渐增大．
A lot of tests of consolidation compression by controlling the sand content and the moisture content have been done for the silt-sand mixed soft soil from the mountain where Jing-mu expressway project is building, with the purpose of studying the effects of these two factors on the soil compressibility. The test results show that the compression modulus of it has a positive correlation to the sand content and a negative correlation to the moisture content; anti-compression has improved significantly in the sand content range （50 % ～70 %）, the compression modulus increased, and the compression coefficient decreased; the compression coefficient is decreasing with the sand content increasing yet increasing with the moisture content increasing.
