本文是通过对黄土质亚粘土、砂垫层及回填土等的地基弹性综合系数的测定而得出的一些研究成果。认为确定地基弹性综合系数值除了考虑基础底面尺寸、地基上单位面积压力等的影响外,在分层土壤情况下,必须考虑下卧层的影响,并提出了近似计算公式;用砂垫层加固软弱地基,其地基弹性综合系数有显著的提高;回填土的地基弹性综合系数,比同类土的天然地基稍低。
In this paper, some research results have been obtained from the determination of the elastic coefficient of the foundation of loess sub-clay, sand cushion and backfill soil. It is considered that in addition to considering the influence of the base floor size and the pressure per unit area on the foundation, the value of the foundation elasticity coefficient should be considered. Under the condition of stratified soil, the influence of the substratum must be taken into consideration, and an approximate calculation formula is proposed. The sand cushion reinforcement is used. In soft foundations, the comprehensive coefficient of elasticity of foundations has increased significantly; the comprehensive coefficient of foundation elasticity of backfill soils is slightly lower than that of natural soils of similar soils.
