锚杆支护在华能大厦基坑中的应用及提高锚杆抗拔力的措施

Application of the Bolt Supporting in Huaneng Building Foundation and the Improvements of Bolt Pull-out Force

本文以华能大厦基坑工程为例,根据场地工程地质条件、水文地质条件,周边环境设施,结合工程条件及施工经验,对华能基坑工程中锚杆施工的钻进工艺、灌浆工艺等方面进行了改进,从而提高锚杆的抗拔力。

To take Huaneng Building Foundation as an example, according to the geological conditions, hydrogeological conditions and the surrounding environment and facilities of the project, the condition of construction and construction experience, this paper evaluates Huaneng pit support project to be the technical feasibility, economic rationality; in other aspects, the improvements of bolt pull-out force has put forward.
