摘要:

基坑支护设计和优化是一项重要而又复杂的工作,采用价值工程理论,通过层次分析及模糊评价原则,对石家庄地铁车站拟采用的多种支护型式进行综合评价分析,得出合理的支护型式及各项支护参数。同时通过分析过程,一方面介绍了利用价值工程原理进行优选分析的计算过程,另一方面通过对比分析粉质黏土及砂地层中放坡与排桩支护、钢支撑与锚索支护的造价变化规律,提出安全、经济、合理的支护形式。

关键词: 基坑工程, 层次分析, 模糊评价, 优化设计

Abstract:

The foundation pit retaining design is an important and complex work. The drawup support methods of foundation pit of Metro station in Shenyang are evaluated and analyzed by means of step analysis and fuzzy comprehensive evaluation principle, and rational retaining type and retaining parameters are obtained. Meanwhile, the calculation process of optimization and analysis by means of value engineering principle is presented, and the cost variation laws of sloping and soldier pile retaining and steel support and anchor support in silty clay and sandy stratum.

Key words: foundation pit, step analysis, fuzzy comprehensive evaluation, optimization design
