摘　　要：目前北京地区基坑支护方式多采用护坡桩,而附着于护坡桩的马道架体又多与护坡桩桩身及锚杆连接,以抵抗架体变形及风荷载产生的水平力。通过实例分析与核算,证明基坑马道对护坡桩的影响满足安全要求。At present, slope protection pile is usually used for support of foundation pit in Beijing, and the berm frame is often connected with slope protection pile and anchor bar to resist the horizontal force generated by frame deformation and wind load. After case analysis and calculation, it was found that the influence of foundation pit berm on slope protection pile satisfies the safety requirement.

关 键 词：基坑马道 护坡桩 锚杆
