Design Optimization Study Of Reinforcing Slope With Anti-slide Pile

Two thirds of our homeland is a mountain, in the vast mountainous topography formed many natural landslide. Along with the rapid development of economy in our country in recent years, the traffic network in the vast land and stretch, road, rail formed a lot of high slope when crossing the mountain, the natural landslide and slope under the condition of engineering measures to reinforce down easily, cause huge losses. Anti-slide pile as a kind of engineering measures, in slope reinforcement engineering, widely applied in landslide prevention and control of geological hazards. However anti-slide pile the engineering structure design theory research work is lagging behind the actual engineering application, especially for various parameters in the design of research and analysis of the influence of less. Mar encountered in hydropower station, this paper segments at a high slope of the research work of this aspect.First studied the slope stability and the anti-slide pile design research status at home and abroad, analysis of the governance are widely used in slope, anti-slide pile in the advantages of anti-slide pile, anti-slide pile is analyzed. Secondly analyzes the anti-slide pile design calculation and design, discusses the general steps of anti-slide pile design and some matters needing attention, and theoretically discusses the landslide thrust, pile spacing, soil retaining plate between anti-slide pile internal force and the calculation and design. Simply introduces the finite element analysis software Midas GTS, theory of software used in the slope stability is analyzed based on finite element method of strength reduction theory, the analysis software used in the constitutive model and the contact element is illustrated, finally the use of finite element analysis software Midas GTS numerical simulation of sensitive parameters in the design of anti-slide pile anchorage length, pile spacing and pile section size on the numerical simulation and analysis, by comparing the conclusion reasonable design parameters are obtained.Results conclusion for mar block hydropower station encountered Duan Bianpo data and basis was provided for design and construction, and also can provide reference for similar slope engineering design and reference.
