预应力锚杆和土钉墙联合支护技术在某电厂基坑支护中的应用

The Application of Combined Support Technology of Prestressed Anchor and Soil Nailing Wall in the Foundation Pit Support of a Power Plant

深基坑支护方案的选取必须对其可靠性、安全性、经济性和实现的难易程度进行综合考虑。某市生活垃圾焚烧发电厂项目工程施工采用预应力锚杆+土钉墙联合支护形式进行深基坑支护,论文对其支护方案、施工工艺以及监测情况进行了介绍。通过监测数据,发现此技术能够满足该地区基坑开挖和支护的安全性,成本也较低,这为同类工程提供了工程经验。

The selection of deep foundation pit supporting scheme must consider its reliability, safety and economy and the difficulty level of realization. The combined supporting technology of prestressted anchor and soil nailing wall is applied in the municipal solid waste incineration power plant construction project in a city, this paper introduces the support scheme, construction technology and monitoring situation, through the monitoring data, the result that this technology can meet the safety requirements of foundation excavation and support in this area is concluded, and the cost is low, providing engineering experience of similar engineering.
