摘要
三峡-葛洲坝两坝间库区急滩多为峡谷型洪水急滩,采用常规的扩大泄水断面等方法进行整治,不仅工程量大,废方多,也难以达到理想的治理效果,而且易引发滑坡等地质灾害。以三峡-葛洲坝两坝间水田角、喜滩两处急滩为例,对库区峡谷型洪水急滩的滩性特点及运用急滩常规整治方法进行治理时存在的局限性进行分析研究。
Most reservoir rapids between two dams of Three-Gorges and Gezhouba are canyon flood rapids.Adopting the conventional rapids regulation methods like enlarging the discharge area to renovate this rapids has many deficiencies,such as producing large quantities,being difficult to achieve better renovation effect and easy to cause localized landslip. Based on Shuitianjiao and Xitan rapids, we analyze the reservoir canyon flood rapids characteristics and limitations of conventional rapids regulation methods.
