| 摘 要： | 云龙河一级水电站厂房后边坡岩性为薄层灰岩夹页岩，节理裂隙等构造发育．在开挖过程中，该边坡顶部开口线与公路边缘地带发现近1cm宽的裂缝，具有明显下滑趋势．结合新老厂址的现场调查，采取敏感性分析确定了物理力学参数，提出了合理的工程措施，并进行了边坡加固前后的稳定分析．该边坡已经受6年多的考验，运行正常，获得了成功．

| Abstract: | The rock of back slope of cascade I power station at Yunlong River is thin interlayer of limestone larding shale. The structure is up-growth, which joint and fissure, and so on. There is a 1 cm width crack along the opening line of the top of the slope and highway edge during the period of digging, and the slope has an obvious slide trend. The authors combined the spot inquisition of lately and old powerhouse site, adopting sensitivity analysis to make sure physico-mechanical parameters, putting forward reasonable engineering measure, carrying on the side slope to reinforce in front and back of stability analysis. The side slope has already been subjected to the test for more than 6 years, operating normally, acquiring success. |
