摘要
本文利用土的非线性次弹性模型,并考虑桩土相互作用,加入接触面单元,编制了有限元计算程序 MYK,考虑了工程实际中分步开挖、支撑等一系列施工过程,利用工程实例对该程序进行了验证,实测结果与理论计算值两者较为接近,得出了一些有实用意义的结论,为工程的设计和施工提供重要参考。
This paper introduces the finite element program MYK developed by using non-linear model and surface unit.This new program can analyze and simulate the process of the excavation of the braced pile.The analyzed results obtained by the calculations fairly approach the measured values achieved from a project in Tianjin.The analysis results are basically in accord with the field monitoring data.Thus they serve as an important reference to the design and construction of the project.
