摘　　要：小浪底水库蓄水10多年之后,库水位的上下变化,导致库区部分库段的库岸坍塌,给当地群众生命财产造成威胁。为合理、准确运用卓洛塔廖夫图解法对小浪底水库区塌岸进行预测,选择柳树滩村为典型案例,在充分考虑该段区地形、地貌、水文地质环境条件以及水下堆积浅滩、水库塌岸和堆积的综合作用的基础上,确定所需要的坡角、波浪爬升高度以及堆积系数等参数。卓洛塔廖夫图解法可适用于小浪底库区黄土状土质岸坡塌岸预测,操作相对简单。该点所预测的塌岸宽度对比现场地质调查结果情况,预测结果符合实际情况,为下一步工程处理措施提供了科学的依据。After Xiaolangdi reservoir impounding for more than 10 years, the water level of reservoir banks in reservoir area changes up and down, leading to reservoir bank collapse which poses a serious threat to the local people’s lives and property. In order to reasonable and accurate using Zolotaleov graphic method on the bank collapse forecast of Xiaolangdi reservoir area,the writer choose Liushutan village as typical cases. In order to determine that the needs of the slope angle, waves altitude and coefficient of accumulation parameter etc., topography, geomorphology, hydrological and geological environment conditions, underwater shoal, reservoir bank collapse and accumulation need to be fully considered. Zolotaleov graphic method is relatively easy operation that can be applied to the bank collapse forecast of loess soils of Xiaolangdi reservoir area. The results of forecasting bank collapse width contrast with the actual geological investigation tally with the actual situation and provides scientific basis for the next engineering treatment measures.
