摘要
基坑开挖是一个复杂的地质工程问题,它既涉及到基坑的自身强度与稳定性,又包含了地质环境和社会影响问题[1]。在基坑开挖过程中,除了要保证基坑的安全,使坑内与坑外的各种工程顺利施工,还要保证相邻建(构)筑物和地下管线等设施的安全。本文根据基坑开挖施工的特点,结合实际工程案例,建立施工动态仿真数值模拟分析计算模型,借助于大型软件MARC对基坑进行施工过程的动态数值模拟,并证明了该方法是准确有效的。
Unloading of excavation is a comlplex problem in landload engineering.It involves not only the intension and the stability of the excavation itself, but also the environment of geography and society effect. In the processs of unloading, it must ensure the safety of excavation in order to make the construction mooth in and out of the excavation ,and ensure the safety of existing building and buried pipeline. This paper,based on the specialty of excavation unloading, establishes the constructing dynamic simulation numerical value analysis and calculation modeling, combines practice cases,and uses the large software MARC to simulate the processs of dynamic numreral.And the precision and efficiency are finally proved in this paper.
