黄河某水库塌岸预测研究

Study on Forecasting of Collapse of a Reservoir on Yellow River

水库塌岸导致沿岸植被破坏,水土流失加剧,对当地的经济及环境产生影响,因此必须对其作出预测,定量估计塌岸宽度。通过对某水库详细的地质调查,总结出该区存在冲蚀磨蚀型、坍(崩)塌型、滑移型3种主要的塌岸模式,并对塌岸发生的影响因素进行了分析。通过采用卡丘金塌岸预测方法,对该库区进行塌岸预测,其结果是可靠的,为选定工程处理措施提供了科学的依据。

Reservoir bank collapse results in vegetation destruction on bank, worsens soil - water loss, impacts local economic and environment. The prediction is important to estimate the width of the bank ruin quantitatively. The detailed geologic survey was made on a reservoir and it was summarized that there were three main bank - collapsing types in this region, including wash and abrasion type, soil collapse （ rock sliding） type, slope type. And the influencing factors of bank - collapsing were analyzed. By using Kaqiujin forecasting method, the collapse of a reservior area on Yellow River was well forecasted. The results were reliable and provided scientific evidence for selecting the project treatment methods.
