摘要
本文采用弯曲剪切扭转有限元模式与杆系有限元增量法相结合分析圈梁效应。从圈梁作用机理、圈梁截面优化、圈梁效应与基坑边长的关系三方面对基坑支护桩结构圈梁进行优化设计。
In this paper,Timoshenko beam element and linear torsional element are adopted for ring beam.Then it is combined with nonlinear finite element method based on Winkler model.The effect and its optimization of ring beam in soldier pile support system in deep excavation is analyzed which includes the mechanism of the optimal section design of ring beam as well as the relationship between length of pit and ring beam effect.
