| 摘 要： | 以南水北调东线穿黄河工程南干渠0+420标段特征断面为例,分析大型渠道土质边坡的极限坡高与设计坡角,确定合适的开挖坡度与坡高。根据三轴试验确定岩土体力学参数取值,并结合国内类似边坡工程取值经验寻求合理的计算参数。建立考虑不同条件下的安全系数表达式,搜索该边坡在地下水位变化条件下多种工况的最小安全系数及相应的危险滑面,并进行对比分析,得到对大型渠道土质边坡稳定性研究有益的结论。

| Abstract: | The characteristic section 0+420 of the southern main canal of the tunneling project across Yellow River for the Eastern Route of South-to-North Water Transfer Project was taken as an example.The limit slope height and the design slope angle of soil slopes for large-scale canals were analyzed so as to determine appropriate excavation slope angel and height.The geotechnical mechanical parameters for rock/soil were determined according to triaxial tests,and based on the experience for the values in similar sl... |
