Plaxis在深基坑支护结构位移评价中的应用

长期以来，工程地质学被看成经验性学科，对大多数复杂工程地质问题只能做出定性的评价，现代工程建设越来越大，场地条件越来越复杂，随之产生的工程地质问题也日益增多。对这些问题进行分析评价时采用传统的解析法求解偏微分方程是不可能的，因而数值分析方法得到广泛的应用。本文通过工程实例，采用Praxis软件对基坑工程支护结构位移进行数值模拟，并结合监测数据进行了对比结果。对深基坑支护结构位移评价具有一定的参考意义。

The Application of Plaxis in the Evaluation of Deep Foundation Pit Supporting Structure Displacement

For a long time,engineering geology has been considered as an empirical subject.For most of complex engineering geology problems,it can only make qualitative analysis.However, the size of modem construction is bigger and the construction site conditions are more complex over the time,engineering geology problems are also become much more complicated.Because these issues cannot be solved by traditional differential equations, numerical analysis method has been applied widely.Based on practical engineering,this article established numerical simulation of deep foundation pit supporting structure displacement by applying Plaxis software; simultaneously, we analyzed results by combining with monitoring data.The final results will help to evaluate the feasibility numerical simulation model method and propose the significance conclusions.
