一、概 述 水坠法筑坝是属于一种湿法筑坝。在六十年代初期,广东省已开始用风化残积土建造水坠坝。当时我们称为半水力冲填法筑坝,但这一筑坝方法没有得到发展。迨至1975年陕晋两省用水坠法筑坝的先进经验传入我省,水坠法筑坝在广东才再次兴起。据不完全统计,到1983年底已建成水坠坝60余座,遍布全省各地。已建成的水坠坝最大坝高68米,最大库容8千多万立米,其中坝高50米以上的有8座,40～50米的有10座。
First, an overview Water fall law dam belongs to a wet dam. In the early 1960s, Guangdong Province started to use water weathered residual soil to build water crashed dams. At that time, we called the semi-hydraulic impounding dam, but this dam has not been developed.迨 to 1975 Shaanxi and Shanxi provinces using water fall method of dam advanced experience imported into our province, water fall method of dam construction in Guangdong only once again rise. According to incomplete statistics, by the end of 1983, more than 60 water-dropping dams have been built across the province. Has built a water dam the maximum dam height of 68 meters, the maximum storage capacity of more than 80 million cubic meters, of which dam 50 meters above the 8, 40 to 50 meters have 10.
