桩锚支护技术在黄土坡地基坑工程中的应用

Application of Pile-anchor Supporting Technology in Foundation Excavation Engineering of Loess Slope-land Region

以一个台阶状黄土坡地的基坑工程为例,基坑三面放坡,一面顶部有较高土坡、挡土墙,采用了灌注桩、锚索支护技术。对桩锚设计和施工中关键技术进行了详细介绍。监测结果表明,各项指标均在设计要求范围内。

Based on the excavations engineering of a loess slope-land region, the excavations slope is put on three sides, one side top with higher slope and gravity retaining wall adopts the pile and anchor cable retaining technology. This paper introduced the key technologies in design and construction of pile anchor. The monitoring results show that the index can meet the design requirement.
