Application Of Network Parallel Electrical Method Based On ANSYS/Emag In Slope Monitoring

Slope stability monitoring has always been the key research object of highway slope eng-ineering.How to intuitively,accurately and quickly analyze the stability of slope body structure is the premise of accurate warning of landslide disaster.At present,the more commonly used method of slope monitoring is to judge the stable state of the slope by monitoring the overall settlement of the slope and the local displacement of the slope body,and make a comprehensive analysis of the stability of the slope structure by combining rainfall monitoring and groundwater monitoring.However,this type of monitoring method has many shortcomings,such as the operation of observation instrume-nts relies heavily on artificial,easy to produce operating errors,low monitoring frequency,for su-dden inducement(such as large rainfall,earthquake,etc.),can not be timely accurate analysis of slope structure changes and other problems.In this paper,based on "based on electrical difference of slope monitoring imaging technology and equipment research and development" project,the in-troduction of the network parallel electrical technology of geophysical exploration course,puts f-orward a new method of slope monitoring,it is using electric technology in rock and soil mass ins-ide the slope structure crack expansion,slip band development,changes of resistivity value caused by rain when the sensitivity of the internal structure change of slope in re-areal-time monitoring.Network parallel electrical device technology is a mature and complete electrical technology syst-ematically,with high sampling rate,large amount of data,many advantages,such as extreme ways with later data analysis simple and intuitive,and the inversion results high reliability advantages,based on the numerical simulation and experiments to study outside reference network parallel electrical technology1.Summarize and summarize the classification,advantages and disadvantages of convention-al slope monitoring methods,and compare and analyze the advantages and disadvantages of netw-ork parallel geoelectricity technology in monitoring methods.2.The theoretical basis and conventional sampling methods of geoelectric technology applied in slope monitoring are described,and the technical characteristics,system devices and inversion methods of network parallel geoelectric technology areintroduced,which provide a basis for the monitoring principle used in this paper.3.The off-site slope experiment based on the network parallel geoelectric technology was carried out.Ansys was used to carry out forward simulation by comparing the off-site experiment results,and Res2 d was used for inversion simulation.4.Focusing on the monitoring means of network parallel geoelectric technology,this paper proposes three different pole distribution modes.Ansys/Emag and Res2d/3d are used to carry out the comparison of forward and inverse monitoring simulation of different pole distribution modes under the same basic model,so as to analyze the advantages and disadvantages of each pole distri-bution method in the process of slope internal slip belt monitoring and the applicable types of slo-slope.
