Abstract: The parameter is used to explain the relationship between pore over pressure and stress in saturated rock-soils under triaxial compression.This is an important subject in the studies of anomalous mechanism of underground water level in a well before an earthquake.In this paper,on the basis of results from laboratory and field test,and of some date of observation in a well,the influences of rock or soil characteristics and loading rate upon the parameter have been researched.

摘要: 孔隙压力参数是用来表述饱和岩土受力变形时所受力与超孔隙压力关系的参数,是地震地下水前兆机理研究中的重要问题。本文从室内试验、现场试验与野外观测的某些结果,分析了不同岩土、不同受力条件下孔隙压力参数的若干特征。
