Anti-slide Pile Of Soil Arching Numerical Simulation Study

With the rapid economic development in China in recent sdaolcimsiesfotcapmiehthcraesreyears, especially since theimplementation osdaolcimsiesfotcapmiehthcraresef the western development strategy, investment sdaolcimsiesfotcapmiehthcraeserin the construction of manyprojects quickly, and with the reduction of urban construction land, more and moreconstruction projects will be moved to the mountains which has is inevitable. In theconstruction of these projects will inevitably encounter many problems slope reinforcement.Stabilizing piles against sliding as an efficient and more economical means, has beenrecognized by many scholars and experts and is widely used in practical engineering. Thepresence of soil arching effect has been widely acknowledged among anti-slide pile of soil,but the problem still exists in many of the conservative anti-slide pile design, which caused aserious waste. Also research the impact of seismic loads for soil arching effect against theslippery pile of conduct still relatively small. The country is an earthquake-prone country,every occurrence of earthquakes have caused some harm to existing projects, and even causeirreparable damage to the project directly. Therefore, this article in such a context, the actualproject as the basis to establish a numerical model, the model is divided into static dynamicanalysis under seismic loads and thrust by changing the decline, anti-slide pile spacing andpile section width to compare Analysis of Pile different soil arching effect, the paper specificwork as follows:(1) the establishment of a numerical model of static through MIDAS/GTS numericalsoftware, change the downward thrust, skid mounted pile spacing width comparison andcross-sectional analysis of the impact of anti-slide pile of soil arching, come under the energyaction against the slippery piles under different conditions influence of soil archingconclusions, and compared with the results of previous studies.(2) into a set of seismic waves on the basis of the numerical model of static, dynamicnumerical model formed under seismic loads. Dynamic numerical model were established atdifferent thrust decline, pile spacing and pile section width, the analysis under differentconditions stabilizing piles and soil arching differences with the results obtained under staticloads contrast, are summarized in under seismic loads anti-slide pile fell in different thrust,different pile spacing, the distribution of the different soil under the pile section width archingeffect. And to provide a reference for the seismic design of future anti-slide pile.
