摘　　要：结合重庆地铁6号线冉家坝车站明挖基坑的设计实例,利用F-SPW6.0软件对该基坑围护结构进行分析设计,包括板肋与锚杆、排桩与锚索的计算;通过当地岩土工程专家的专题论证以及施工中监控量测结果的对比分析,表明基坑设计可靠、安全,其设计方案对类似地质条件的大型、复杂超深基坑的设计具有很好的借鉴意义。Combining with the design case of open-cut foundation pit of Ranjiaba Station in Chongqing Metro Line 6,the main support structure of foundation pit is analyzed and designed by using F-SPW6.0 software,including the calculation of plate rib and bolt,as well as the calculation of row piles and anchor cable. By the special demonstration of local geotechnical engineering experts,and compared with the monitoring measurement results in construction,it shows that the design of foundation pit is reliable and safe.
