五强溪水电站左岸船闸边坡综合治理方法
|
摘要
分析了五强溪水电站左岸船闸边坡岩体结构特征,介绍了基于工程地质力学综合集成方法论所形成的综合治理的方法。提出了在阻断或削弱引起边坡变形的外在因素的基础上,通过工程处理与加固,以达到提高其边坡稳定性之目的的五强溪边坡治理模式。作者还以大量的监测资料对该边坡综合治理的效果作了论证。该边坡治理设计思路和采用的加固技术,可望为同类条件下的边坡设计和施工提供借鉴。
This paper present a treatment method of slope based on the EGMS (Engineering geomechanics meta-synthetic method) and characterization of the structure of natural rock mass on the left bank ship-lock slope of Wuqiangxi Hydropower Station. The author proposes a treatment solution that improves the slope stability by engineering disposal and local strengthening in addition to reducing or control external factors that causes deformation of the slope. Detailed monitoring results are also presented to demonstrate the effectiveness of the synthetic treatment. Such a successful treatment experience of the complicated slope provides a good example for engineers in the field of hydropower engineering.
