摘要
为研究不同轨道交通基坑支护方案的工程造价,基于昆明轨道交通五号线工程土建四标段项目,对地连墙加高与钢板桩支护 2 种施工方案进行安全系数分析、工期分析以及造价分析;研究结果表明,钢板桩支护方案具有较高的安全系数、较短的工期以及较低的造价,研究结果对制定类似工程的基坑支护方案具有借鉴意义.
Abstract
In order to study the engineering cost of different supporting schemes for the foundation pit of rail transit,based on the civil construction project of kunming rail transit line 5,based on the factor of safety analysis,time limit analysis and cost analysis of the two construction schemes of diaphragm wall heightening and steel sheet pile support,the research results show that,the steel sheet pile bracing scheme has higher factor of safety,shorter construction period and lower cost,which can be used for reference for the foundation pit bracing scheme of similar projects.
