对雅砻江流域某拟建电站库区边坡失稳后的滑速和涌浪高度进行计算。计算滑速采用潘家铮条分法,涌浪高度计算同时采用水科院经验公式法和潘家铮法两种方法。综合两种方法的计算结果获得库坝处滑坡产生的涌浪高度为0.41~0.88m,对拟建工程影响较小。此计算分析方法对类似工程具有借鉴意义。 The slippery speed and surge height of the slope of a proposed power station in Yalong River Basin after instability are calculated. The calculation of sliding speed using Panjiazheng piecewise method, the calculation of the surge height at the same time using the CASS empirical formula method and Panjiazheng two methods. According to the calculation results of the two methods, the wave height of the landslide at reservoir dam is 0.41 ~ 0.88m, which has little impact on the proposed project. This method of calculation and analysis can be used as reference for similar projects.
