中文摘要：

以西南一城市综合换乘枢纽站改造深基坑支护工程为例,结合工程所在区域的地质条件、场地情况和周边环境,重点分析了板肋式锚杆挡土墙锚杆、肋柱、挡土板的设计方法和施工程序,并建模计算了支护结构的内力和加固效果。结果表明,板肋式锚杆挡土墙支护能改善基坑整体和局部稳定性,可为类似工程提供参考。

英文摘要：

Taking the deep foundation pit support reconstruction engineering at the transfer hub station in one southwest city as an example,the bolt,rib-column and retaining plate design methods and construction procedures for ribbed plate-type bolt retaining wall supporting were analyzed. The internal force and reinforcement effect of support structure were modeled and calculated by considering the regional geological conditions,site conditions and the surrounding environment of the project. The results showthat ribbed plate-type bolt retaining wall supporting could improve the overall and local stability of foundation pit and could provide a reference for similar projects.
