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 struc-ture design and reasonable selection of construction methods are necessary.Taking a case of foundation pit supporting engi-neering, 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.
