The invention relates to a slope rock-soil body electrical parameter spatio-temporal evolution test system and method, and the system comprises an electric field applying device which is used for generating a uniform electric field in a slope, an electrical parameter acquisition device used for testing the voltage of the rock-soil body between the electrodes and obtaining current data of a measurement point by combining the current field intensity, and an external load applying device used for applying various external loads to the side slope and simulating the state of the side slope under the action of the loads. Compared with the prior art, the system has the advantages that the spatial-temporal evolution of the electrical parameters of the slope soil body under the action of various loads can be rapidly tested, and the electrical parameters of the slope soil body under the action of various loads are obtained.
Description
technical field [0001] The invention relates to the field of civil engineering, in particular to a system and method for testing the temporal and spatial evolution of electrical parameters of slope rock and soil mass under the joint action of multiple loads. Background technique [0002] Under the action of complex loads, the physical and mechanical properties of slope rock and soil change, and natural disasters such as landslides and collapses are extremely prone to occur. Resistivity, which characterizes the electrical conductivity of rock and soil, is correlated with microstructure and physical and mechanical properties. Field slope surveys usually use the Wenner equidistant quadrupole method or the Schlumberger-Palmer unequal-distance quadrupole method to measure the apparent resistivity, and then obtain the resistivity layered structure through rock and soil inversion. [0003] After retrieval, Chinese Patent Publication No. CN110940794A discloses a comprehensive test ...
