Abstract
The application discloses a kind of anisotropic synergic deformation three-dimensional earth pressure measuring device and method, it is related to piezoresistive earth pressure measuring technical field.The device includes earth pressure cell, the earth pressure cell includes shell, monitoring electrode and filling component, the shell is square, several filling components are arranged in shell, the filling component is composed of conductive rubber spacer block and steel ball, several conductive rubber spacer blocks are arranged around each steel ball, the monitoring electrode is arranged on the inner wall of shell, monitoring electrode is arranged on each face of shell, the steel ball and conductive rubber spacer block fill the inside of shell, the outermost conductive rubber spacer block and monitoring electrode are closely adhered, and the earth pressure is obtained by calculating the resistance value measured by monitoring electrode.The filling component with the same rigidity as the tested soil is used for piezoresistive measurement, the earth pressure in different directions can be monitored simultaneously, and the problem of anisotropic synergic deformation measurement of soil is solved.
