摘　　要：建立岩土的工程力学性质与其地球物理参数的量化关系是实现工程物探资料量化解释的必然前提 .本次工作在分析影响土的工程力学性质和电阻率的共同因素基础上 ,通过室内实验 ,研究了不同类型土的粒度成分、含水率、饱和度、密实度与其电阻率的关系 ,并在此基础上探讨了粘土的压缩系数、粘聚力、压缩模量与电阻率的关系 ,得出了一系列的关系曲线及一些拟合公式 ,并对这些公式的含义进行了解释 .It is a tendency to study the correlation of geophysics parameters and engineering properties of rock and soil, in order to make the numerical interpret of engineer geophysics possible. On the basis of analysis of the common factor between engineering mechnical properties and resistivity of soils ,by experiments, we study the relation between resistivity of soil and its granularity、water content、saturation degree、consistence. We also study the relation between the electrical resistiviy of clay and its compressible coefficient 、cohesion、modulus of compressibility. In final we get some curves 、formulas and their explanation.

关 键 词：土的电阻率 土的粒度 土的含水性 土的密实性 土的力学性质
