结合北京某研发楼工程,介绍了预应力锚杆复合土钉基坑支护结构的方案设计及施工方法,通过基坑支护监测,分析了基坑坑壁水平位移和锚杆拉力的分布情况,指出采用土钉墙和预应力锚杆复合土钉支护可提高基坑的安全性。
Combined with a research and development building project in Beijing, the scheme design and construction method of prestressed anchor composite soil nailing pit supporting structure are introduced. Through the foundation pit support monitoring, the distribution of pit wall horizontal displacement and anchor tension It is pointed out that the use of soil nailing wall and prestressed anchor composite soil nailing support can improve the safety of foundation pit.
