深基坑开挖过程的动态模拟设计

Design of the Dynamic Simulated Process in Deep Excavation

利用现代计算机仿真技术,采用适当的土与支护结构模型和弹塑性有限元理论,编制了动态模拟深基坑开挖过程的程序,并结合工程实例进行计算分析,对深基坑开挖过程中可能出现的险情进行有效的事先预测,检验现有施工方案的可行性,为工程设计和现场施工提供了理论参考和指导.

With modern computer emulational technology,based on the theory of elasto-plas-tic finite element,a program for simulating the excavating process of deep foundation pit is presented,in which suitable model for soil and supporting is adopted.As the effective fore-cast of dangerous case which would happen possibly in the process of deep excavation is re-alizated and the feasibility of constructive precept is checkouted,the method may serve as a theoretical reference and practical guide for engineering design and site work.
