| 摘 要： | 在坚硬岩体中施工大直径抗滑桩非常困难，需要安全有效的结构设计和合理施工方法的选择。以某基坑支护工程实践为例，大胆创新支护桩结构设计方案，通过在坚硬岩段采用微型钢管群桩代替大桩方案的变更设计，改进了施工工艺，有效地克服了在坚硬岩体中施工大口径桩嵌岩困难的问题，满足了原设计中的嵌岩深度，达到了支护效果。

| Abstract: | It is very difficult to the construct large diameter anti-slide pile in hard rock mass, the safe and effective structure design and reasonable selection of construction methods are necessary. Taking a case of foundation pit supporting engineering, with innovative supporting structure scheme, using micro steel pipe piles instead of large pile in hard rocks, and these improved technology effectively overcame the difficulties in large diameter rock-socketed pile construction and met the requirements of original design to achieve the supporting effect. |
