老挝南欧江五级水电站枢纽区边坡设计

Slope Treatment Design for Nam Ou 5 Hydropower Station in Laos

老挝南欧江五级水电站边坡高,地质条件复杂,边坡稳定性较差。通过对原始边坡反演分析,确定了合适的岩体物理力学参数。根据边坡失稳模式采用多种方法进行边坡稳定分析,提出了较为经济合理的边坡处理措施,最大限度地节约了工程投资,也保证了工程的顺利推进。

The bank slopes of Nam Ou 5 Hydropower Station in Laos are high, the geological conditions are complex and the stability of slopes is poor. The reasonable physical mechanical parameters of rock mass are determined through the inversion analysis on original slopes. According to slope instability model, the slope stability analyses are also carried out by using a variety of methods. Reasonable and economic slope treatment measures are finally put forward, which can not only maximize the saving of investment, but also ensure the smooth progress of project construction.
