沈阳地区深基坑开挖条件下抗拔桩承载力检测分析

Testing analysis on uplift pile bearing capacity under deep foundation conditions in Shenyang region

以沈阳某商业楼为例,根据试验桩的实际检测结果,对地面、坑底抗拔桩的极限承载力特点进行了分析,指出单桩极限承载力的消弱可达19.2%,为今后沈阳地区埋头桩的设计提供了参考依据。

Taking the commercial building in Shenyang as an example, according to actual testing pile detection results, the paper analyzes ultimate bearing capacity features of ground surface and bottom foundation uplift pile, and points out that ： the ultimate bearing capacity of single pile can be reduced by 19.2%, which has provided some guidance for embedded pile design in Shenyang region.
