盐渍土独特的工程特性为盐渍土地区公路的设计与施工带来较多不便。结合现场取样与室内试验,研究了不同含水率、含盐率、压实度下盐渍土承载比CBR与土基回弹模量E_0的推导关系。发现各因素下CBR-E_0关系曲线拟合良好,且不浸水CBR-E_0拟合相关系数优于浸水CBR-E_0。基于大量试验数据,最后提出了基于含盐率和压实度的盐渍土土基回弹模量的取值推荐。 The unique engineering features of saline soil bring more inconvenience to the design and construction of highway in saline soil area. Based on the field sampling and laboratory tests, the relationship between CBR of salinized soils and the modulus of elasticity of soil foundation, E_0, under different moisture content, salt content and compaction degree was studied. The correlation curve of CBR-E_0 under various factors was found to be well fitted, and the correlation coefficient of CBR-E_0 fitting was better than that of soaking CBR-E_0. Based on a large number of experimental data, the recommended value of the elastic modulus of the saline soil based on salt content and compaction degree is proposed.
