The Application Of Antislide Pile Used In Engineering Of Accumulation Landslide

Landslide is a very common natural disasters, human engineering activities, theconstruction of dams, underground excavation, reservoir storage and other slope instabilityleading to an important reason, after years of engineering practice and theoretical research,prevention and treatment of landslide has very great achievements, particularly the rapiddevelopment of anti-slide structure applications. Friction piles which are an effectivemeasure for controlling the landslide have all important position in treating the landslide inall countries of the world and more and more widely used in engineering area。Supported by the projects of Da Yaogu landslide in the Three Gorge reservoir region,the thesis has carried out a study on the dynamic response of the debris landslide by meansof the numerical simulation software-ABAQUS. Finally, the supporting measures of the DaYaogu landslide is carried on optimized control. The mainly research results in my paperwriting are as follows:1. It is found that gravity, complex water environment and earthquake dynamic factorare the major revival factors of debris landslides by analysis of the basic features anddynamic displacement features of debris landslides.2. Investigated on the geological conditions of the typical debris landslidessystematically, for instance, geological settings, hydro geological conditions, terrainfeatures. The effects on the dynamic stability of landslide which is induced by theseengineering geological conditions is analyzed in detail.3. Three different retaining control measures were selected to protect the landslide. Thefinally different support effects have been obtained by using numerical simulation methods,then the most reasonable retaining control measures which is used to resistant to seismicload is determined through comparing the permanent displacement, velocity amplificationand the minimum safety factor under every condition.4.Using strength reduction method in ABAQUS to determine the reasonablearrangement of anti-slide pile and supply foundation for engineering。...
