摘　　要：利用设计软件FRWS4.0,对北京地铁4号线马家楼站主体基坑围护结构进行计算,针对不同桩型分别得到对应的锚索拉力值;试验数据证明,预应力锚索是可靠的,在施工过程中进行锚索张拉试验,表明锚索的施工可以满足设计要求,主体结构的施工工期大大缩短,工程收到了预期的效果。Software FRWS 4.0 was used to calculate the excavation pit support of Majialou Station on Beijing subway Line 4. Tensile forces in anchor cables for different types of piles were obtained respectively. During the process of construction, pulling out test of the anchor cables was performed and results of the test indicated that the installed anchor cables were reliable and could meet design requirements.
