摘要
深基坑支护方案设计可以为决策者提供多种设计方案,采纳不同的设计方案会实现不同的技术经济效果,为选出最优设计方案,需要对各个设计方案进行技术经济评价与比较,从中选出一个技术经济效果最好的设计方案作为最优方案。本文介绍了一种用来比较和选择深基坑工程支护方案的技术经济评价模型:首先根据现场工程地质、水文地质条件及场地环境等条件研究可行的深基坑支护方案类型,然后对每种支护方案类型进行优化设计,最后利用价值系数分析法对各个优化设计方案进行比较,价值系数最高的优化方案即为最优方案。
For a deep foundation pit supporting project,the designer can provide a variety of design options for the decision maker,and the adoption of different design schemes will get different technical and economic effects.In order to select the optimal design scheme,it is necessary to carry out technical and economic evaluation and comparison of each design scheme.This paper provided a technical and economic evaluation model of comparison and selection for deep foundation pit supporting project.Firstly,studying the feasible pit type of deep foundation according to the research of engineering geology,hydrogeology and environment conditions,then optimize each type of support,and finally compare and evaluate the optimization of different feasible solutions.The solution of highest value coefficient is the optimal scheme.
