【摘要】 土的变形模量是基础沉降弹性分析理论所必需的基本参数,而目前我国的岩土工程勘察报告一般并不提供土的变形模量。通过对前人研究结果的总结分析,基于多孔介质理论,并考虑土的泊松比、孔隙比及土体扰动等影响因素,笔者提出了一种根据土的压缩模量估算变形模量的方法,对于应用弹性理论计算基础沉降和充分利用已有研究资料都具有实际的意义。更多还原

【Abstract】 Deformation modulus of subsoil is an indispensable parameter for calculating settlement of foundation based on elastic theory; whereas the deformation modulus of subsoil is usually not provided in geotechnical investigation reports in China. Previous published researches are analyzed in this paper. An approximate method that considers the influencing factors including Poisson ratio, porosity ratio and remolding of soil, is developed based on porous medium theory. It estimates the deformation modulus of subsoil through compression modulus. It has practical significance in both calculating settlement of foundation with elastic theory and making full use of the existing research data.更多还原
