阿尔塔什水利枢纽右岸高边坡岩体强度参数确定的经验方法研究

在大型水利水电工程中,岩体强度参数是工程设计中的重要参数,强度参数的合理取值对工程设计、施工以及安全复核具有重要影响。新疆叶尔羌河阿尔塔什水利枢纽工程中,右岸高边坡的稳定对于整个枢纽工程具有决定性的作用。在右岸边坡岩体质量调查基础上,利用GSI方法对边坡岩体进行质量评分,结合提出的岩体质量分类标准,进行了右岸边坡岩体强度参数的估算。在参数估算结果基础上,参考我国水利水电工程中现行的工程地质勘查相关规范中给出的各类岩体建议值以及以往工程中相关资料,提出了阿尔塔什水利枢纽工程中右岸高边坡岩体强度参数的建议值。

The application of empirical method to determine the strength parameters of the right bank slope in AERTASHI Hydropower Station

In large water and hydropower projects, how to determine the rock strength parameters has important implications for engineering design, construction, and safety review. In the AERTASHI water project, the right hank high slope stability plays a decisive role in the whole project. On the quality survey of the right bank slope, the slope rock mass quality score was obtained by using the GSI method. And then the right bank slope rock strength parameters were estimated, consideering the rock mass quality classification criteria and the GSI score. Based on the estimated result of rock strength parameters and by referring to the recommended value of various rock mass in related existing specifications of the water and hydropower engineering geological exploration, the right bank high side slope rock mass strength parameters of AERTASHI water project had been presented.
