通过对某水库工程小型滑坡体的稳定分析,提出了3种工程措施,分别为全部挖除、预应力锚固、普通砂浆锚杆锚固,经方案比较,选定砂浆锚杆锚固方案,并进行了加固设计,校核了安全系数。经过半年的观察和跟踪,该滑坡无明显移动,稳定性良好,证明所采取的锚固方案是成功的。该方案投资较小,设备简单,加快了工期,经济效益明显。由此可以证明,对于小工程并非一定要做预应力锚固,而可以选择更为经济、实用的砂浆锚杆。
Through the stability analysis of a small landslide body in a reservoir project, three engineering measures are proposed, which are all excavation, prestressed anchorage and anchor mortar anchoring of ordinary mortar. The anchor mortar anchoring scheme is selected based on the scheme comparison and carried out Reinforced design, checked safety factor. After six months’ observation and follow-up, the landslide did not move obviously and its stability was good. It proves that the anchoring scheme adopted is successful. The scheme has the advantages of small investment, simple equipment, quicker construction period and obvious economic benefits. From this we can prove that for the small project does not have to do prestressed anchoring, and can choose more economical and practical mortar anchor.
