| Land-slide, often taking place in a mountainous area, is a geological disaster with a large quantity and scale. It is very complicated and always has some regularity and often causes severe damages. Usually, land-slides happen in certain engineering circumstance and certain hydro-engineering geology circumstance. It is a kind of slope deformation caused by natural forces, mainly the gravity, or by human project actions.In recently, anti-slide pile with pre-stressed anchor cable as a new pattern structure that now more and more treatment project in sliding slope. As a new structure, It 's design theory and norms are still not well established. Through analysis of anti-slide pile with pre-stressed anchor cable of force against sliding mechanism, analysis of the design theory and methods and optimization theory. Basis on it, use ANSYS software to give a practical project to optimize the design .In this paper, in order to determine anti-slide pile with pre-stressed anchor cable, first on the causes of land-slides and land-slide thrust of the calculation of a summary and analysis, to obtain a different type of land-slide in the form of landslides thrust calculation method. After calculate the land-slide thrust, research the design model of anti-slide pile with pre-stressed anchor cable, and get the best in the mechanical model. carried out a detailed analysis to the design and calculation methods of anti-slide pile with pre-stressed anchor cable , get a reasonable steps to design plans. Then, introduce optimal design theory of anti-slide pile with pre-stressed anchor cable, and research the Parameters-Selection of optimal design . At last , according to the anti-slide pile with pre-stressed anchor cable design theory and structural optimization and design theory,Select a land-slide project, use ANSYS make a optimal design to it, then Get the Economic and reasonable pattern structure for the land-slide, and prove that the theory which discussed in the paper are reasonable. |
