为了查明水工建筑物基础的稳定条件,必须对河谷地质、河谷类型及其形态进行详细的工程地质、水文地质测绘与勘探。而河谷地质、河谷类型及形态等因素是选择坝型的主要依据。工程设计方面可据此作出各种不同类型的坝型比较,最终根据地质上的可能性、工程上的安全性、经济上的合理性来确定坝线与坝型。我国第一座重力拱坝——响洪甸水库已动工兴建了。响洪甸水库位于安徽省金寨县境内渒河(淮河支流之一)西源中上游地方,坝高江淮零点起141.5公
In order to ascertain the stability of the foundation of hydraulic structures, detailed geological, hydrogeological surveying and exploration of the valley geology, valley types and their forms must be carried out. The river valley geology, river type and morphology and other factors are the main basis for the choice of dam type. Engineering design can be based on a variety of different types of dam-made comparison, and ultimately based on the possibility of geological, engineering safety, economic rationality to determine the dam line and dam. China’s first gravity arch dam - ring flood Austin Reservoir has been started construction. Hing Hongdian Reservoir is located in Jinzhai County, Anhui Province within the Bahe (one of the Huaihe tributaries) west of the upper reaches of the source, dam high Jianghuai zero from 141.5 kilometers
