摘　　要：在深基坑支护中采用刚架护坡桩，替代悬臂式单桩，可降低材料用量；替代加锚杆的护坡桩，可节约材料。工程实践表明，应用该技术不设锚杆支护深度达12．6m，嵌固深度仅3m，位移仅4mm。There is a comprehensive introduction about the rigid frame supporting pile's bearing ca-pacity features and its applications.No anchorage bar is used in this construction technology. Its support-ing depth could be reached as far as 12.6m; and its consolidation depth is only 3m,while its displace-ment is only 4 mm.
