Mechanisms of Change in Physical Properties of Soil under Experimental Electrochemical Reinforcement

摘要

The article describes integrated experimental research into mechanisms of change in physical properties of soil under electrochemical reinforcement implemented in a test area. The monitoring methods involved geological engineering survey, laboratory testing of soil samples, as well as statistical, geomechanical, seismic, electrical and georadar sounding. It has experimentally been proved that three zones (strengthening, dehumidification and transient) are formed in the interelectrode space; the ranges of space and time change in humidity, deformation modulus, cohesion, internal friction angle, elastic wave velocities, electrical resistivity and integral parameters of georadargrams are found. The authors substantiate ways of improving efficiency of two-and one-stage schemes of electrochemical soil reinforcement and application areas of geophysical monitoring techniques.
