摘要
为比选不同基坑支护方案,研究不同支护参数下基坑变形控制效果,文章依托某建筑基坑工程,通过层次分析法和模糊综合评判法,对初选的三种支护方案(双排桩支护、地下连续墙、单排桩+锚杆支护)进行比选,并基于有限元模拟分析双排桩不同桩长对基坑变形的控制效果.结果表明,双排桩支护方案为最优支护方案;适当增加桩长,可有效减少桩体水平位移.
Abstract
In order to compare and select different foundation pit support schemes and study the deformation control effect of foundation pit under different support parameters,based on a building foundation pit project,this paper compares and selects three primary support schemes(double-row pile support,underground continuous wall,single-row pile+anchor support)through Analytic Hierarchy Process and fuzzy comprehensive evaluation method,and analyzes the control effect of different pile lengths of double-row piles on foundation pit deformation based on finite element simulation.The results show that the double-row pile support scheme is the optimal support scheme;increasing pile length appropriately can effectively reduce the horizontal displacement of the pile body.
