摘要
为优化综合管廊基坑支护设计,以佛山某综合管廊基坑为例,通过对基坑深度、周边环境和地质条件等影响因素的分析,分段选取安全、经济、合理的基坑支护方案,从而达到优化的目的,并得出如下结论;①精细化和动态化设计是综合管廊基坑设计的必然要求;②管廊结构、基坑深度、周边环境和地质条件等是基坑优化设计的关键要素;③安全适用、经济合理、保护环境、施工快速的基坑支护方案是优化设计的最终目的。
In order to optimize the foundation pit support design of utility tunnel,taking a foundation pit support design of utility tunnel in Foshan as an example,through the analysis of the influencing factors such as the depth of the foundation pit,the surrounding environment and geological conditions,the safe,economic and reasonable foundation pit support scheme is selected by sections,so as to achieve the purpose of optimization,and the following conclusions are drawn:①The refined and dynamic design is the inevitable requirement of the foundation pit design of the utility tunnel;②Utility tunnel structure,foundation pit depth,surrounding environment and geological conditions are the key elements of foundation pit optimization design;③The ultimate goal of the optimization design is the foundation pit support design which is safe,applicable,economical,reasonable,environmental protection and rapid construction.
