Displacement Back Analysis Of Slope And Its Application In Engineering

Slope engineering is rock and soil composed of natural materials and structural engineering surface. As the rock and soil's complex physical and mechanical properties of materials, It is random and uncertain to determine the mechanical parameters of rock and soil by the traditional laboratory tests of sampling and mechanical test site. Therefore, the thesis is carried out studying on back analysis of slope displacement and its application in engineering. By carrying out back analysis on experience and nature state of rock and soil on the slope displacement monitor information can evade the difficulty that the parameter brings about since complexity and a lot of uncertain factors of the rock soil body are ascertained physical mechanics, consider the impact of the various combination of factors from the engineering point of view, anti-performe reproduction of physical behaviors parameters of geotechnical that accurate combine the selected inverse slope model, and evaluation of slope stability effectively which can provided a feasible approach. The thesis works mainly as follows:â‘ In the extensive literature review on the basis of information,this paper expounds the displacement back analysis method of classification,and a detailed analysis of the basic principles of positive and negative analysis used in the articles, establish the methods and principles of defining back analysis of inversion parameters and explore the idea of inversion parameters compression.Clarify the displacement back analysis to establish the principles of the measurement system and method of processing the measurement data, reveal the significance of the displacement back analysis method used in the meaning of slope engineering.â‘¡To implement physical parameters of rock and soil slope inversion by the back analysis calculation through optimization functions in the ANSYS finite element analysis software . Across examples can simulate the slope rock mass elastic modulus, poisson ratio, density of the "equivalent parameter" through calculating slope displacement monitoring data in the ANSYS analysis of inversion,then conducrt forward calculation by use of the the resulting "equivalent parameters" in the calculation model, can calculate in good agreement with the calculated results, verify the information on anti-displacement measurement based on analysis of the feasibility.â‘¢Against displacement back analysis of the landslide located in Shanghai to Ruili Road (Guizhou border) off road environment within the town Ning Zhisheng, then ascertain "the equivalent parameter " of slope soil and rock by calculating. The result can be used to work late or equivalent conditions to predict,compare and achieve the practical evaluation .
