浙东沉积岩顺层滑坡预应力锚索加固治理技术

Design and Construction of Pre-stressed Anchor Cable in the Treatment of Bedding Landslide of Sedimentary Rock in Eastern Zhejiang

在浙江中东部地区,沉积岩分布较广泛,由于层面发育及存在软弱夹层,顺层滑坡时有发生。结合工程实例,对采用预应力锚索加固治理顺层滑坡的设计过程及施工方法进行了分析。监测结果表明治理措施安全有效。

In the Mid-eastetn part of Zhejiang, sedimentary rocks are widely distributed, because of the bedding develop- ment and the weak interlayer, the bedding landslide is often occurring. Based on the engineering example, the design process and the construction method of the pre-stressed anchor cable to control the landslide are analyzed. The monitoring results show that the control measures are safe and effective.
