高层建筑深基坑支护结构三维计算方法研究

Research on Three dimensional Calculation Method for Bracing Structures of Deep Foundation Pit of High rise

在已有的竖向弹性地基梁有限元二维的基础上，提出了竖向弹性地基梁有限元三维计算方法．该法较二维计算方法，计算简明实用，更接近工程实际．不但可以获得较合理的计算结果，而且可以节约工程量，具有明显的经济效益．

Based on two dimensional finite element method (FEM) for vertical beam on elastic foundation, a three dimensional FEM is put forward. Compared to the former, this new method is simple in calculation, practical in use, and more approximate to the engineering practice. By using this method, the calculation results will be more reasonable and the project cost will be decreased. Therefore it has obvious economic benefits.
