摘要
水平荷载作用下桩-土作用机理十分复杂,伴随着计算机技术的发展,数值计算法可以帮助实现准确拟合桩-土的相互作用关系。基于此,如何建立合理的有限元计算模型,选取相关的计算参数等都是影响数值分析正确性的主要问题。文章通过结合室内实验和有限元数值模拟,验证小区域土体受到边界条件影响时土体模量是变化的这一结论,总结出桩体受往复水平荷载条件下力-位移关系,为工程研究提出一些参考依据。
The mechanism of pile and soil under the action of horizontal loading is very complicated,but with the development of computer technology,numerical calculation method can help us to achieve accurate fitting of pile - soil interaction relations.Therefore,how to establish a reasonable finite element calculation model,and select relevant calculation parameters are the major problems of affecting accuracy of numerical analysis.By combining the indoor experiment and finite element numerical simulation,the conclusion can be validated that the soil modulus of soil is changing when small area affected by boundary conditions,the pile dint force-displacement relationship reciprocating horizontal load conditions is summed up yet,to put forward some reference for project research.
