【摘要】 作为基坑支护设计、变形分析的重要方法——连续介质有限元法不仅具有强大的数据分析和图形显示功能,而且能够充分考虑基坑设计与土方开挖过程的许多影响因素,计算土方开挖对周围环境的影响。本文以南京某深基坑工程为例,首先采用有限元法进行建模分析得出周边环境的变形,然后结合现场实测数据验证模型的可靠性,最后进一步分析得出基坑变形相关影响因素。更多还原

【Abstract】 Continuous medium finite element method,as an important method for foundation pit support design and deformation analysis,is not only has the powerful data analysis and graphics display function,but also can fully consider many factors,in supporting the design and earthwork excavation process,calculate the impact on the surrounding environment.This paper takes a deep foundation pit engineering which in Nanjing as an example,first,by using the finite element method modeling analysis,get the modification of the environment,then combined with field data to verify the model reliability,finally,analysis of the factors affected by excavation deformation.更多还原
