桩锚和土钉联合支护在某基坑设计中的应用研究

Application and research of pile-anchor and soil-nailing combined supporting in some foundation pit design

结合某深基坑设计实例分析,详细介绍了桩锚土钉联合支护工作机理、设计内容,通过现场监测结果及实践运营,验证了桩锚土钉联合支护效果,说明该方案是可靠和可行的,为类似条件下桩锚和土钉联合支护基坑设计提供了参考依据。

Combined with the analysis and design example of a deep foundation pit are introduced in detail, the pile anchor and soil nailing sup- port working mechanism, design content, through the site monitoring results and practical operation, to verify the pile anchor and soil nail sup- porting effect, show the scheme is reliable and feasible, which provides the reference for the similar conditions of pile anchor and soil nailing sup- port the design of foundation pit.
