Soft Performance Of Horizontal Bearing Capacity Of Pile Foundation

For the study of the soil pile under lateral load mechanism just50years of history,the traditional static load test often do not reach the level of the ultimate limit will beterminated, and the use of numerical analysis is often because of the oversimplificationof the model and the actual results to differ materially. So far, about the level of pilebearing capacity of soft ground is still relatively backward.In recent years, the rapid development of China’s road and bridge construction. Inthe nearby area, inland river bridges, foundations tend to have low bearing capacity,high water content, high compressibility, creep characteristics. Pile foundation for itsable to adapt to a variety of complex terrain and other features have been widely used.In the operation of the bridge may be horizontal load: wind loads, wave loads, cranesystem, seismic loads, ice floes and power, ship impact force, these horizontal loadsmay cause the bridge structure and function failure or cause accidents. To solve thisproblem, this paper for practical engineering background to, Doumen yellow, ZhuhaiCity, Guangdong Province, Mirror Gate Bridge, using ANSYS finite elementsimulation of the actual project a combination of analytical methods, hosted the levelof bridge foundation built in the kind of soft ground performance of the force to dorelated research and research work and conclusions are as follows:Comparative analysis of different loads, different pile diameter and strength ofconcrete pile design parameters such as the level of pile bearing capacity of differentload curves of different pile diameter and strength of concrete pile horizontaldisplacement distribution law and pile Torque Distribution Rule curve. Come to the topof the pile horizontal load pile horizontal displacement greater impact, increasing thepile diameter was a substantial raise the level of pile bearing performance, increase thepile of concrete strength the pile horizontal bearing performance improvement smallerconclusion. Comparative analysis of different Poisson’s ratio, elastic modulus and internalfriction angle and cohesive force of soft soil parameters on the level of pile bearingperformance, different Poisson’s ratio, elastic modulus and internal friction angle andcohesion under the pile horizontal displacement distribution law of the curve andbending moment distribution law curve. Draw the angle of internal friction bearingperformance was less affected, Poisson’s ratio have a more significant effect on thebending moment on the soft ground level, cohesion maximum horizontal displacementin the top of the pile have a greater impact, the elastic modulus control softwareland-based horizontal bearing capacity of the main factors relevant conclusions.From the pile and soil constitutive theory, pile diameter actual size and otheraspects of the error analysis ANSYS numerical simulation calculation results with theactual engineering data, results show that the error is within the scope of the projectlicense, and thus verify the method used herein reasonable.
