边坡高层建筑施工中基坑排桩方案的优化及分析

Optimization and Analysis of the Pile Avrangement Scheme of Foundation Pit in Constraction of High-rise Building on Slope

本文依据灰色模糊理论构建边坡高层建筑基坑排桩方案优化模型,对基坑排桩方案进行优化,提升其方案实施整体效果。先构建了灰色模糊隶属度,并以此为基础构建灰色模糊可变决策模型。利用信息熵法和层次分析法完成评价指标的选定及权重的确定,构建完善的边坡高层建筑施工基坑排桩方案评价指标体系,对方案进行评价。实验结果表明:其得到的方案与实际采用的方案是一致的,该方法有对基坑排桩方案择优选择的能力。

Based on the grey fuzzy theory,this paper constructs the optimization model of the pile arrangement scheme of the foundation pit of the high-rise building on the slope,optimizes the pile arrangement scheme of the foundation pit,and improves the overall effect of the implementation of the scheme.Firstly,the gray fuzzy membership degree is constructed,and then the gray fuzzy variable decision-making model is constructed based on this.The information entropy method and the analytic hierarchy process are used to complete the selection of the evaluation indicators and the determination of the weights,and build a perfect evaluation index system for the pile arrangement scheme of the foundation pit of the high-rise building construction on the slope,and evaluate the scheme.The experimental results show that the obtained scheme is consistent with the actual scheme,and the optimization of the pile arrangement scheme of the foundation pit can be carried out in this paper.
