一、前言 我省在50年代末至60年代初,已成功地用水坠法建成揭阳县的盘峡、广州市郊区的筲箕窝等水坠坝,当时称为土法水力冲填坝或半水力冲填坝。1975年陕、晋建造水坠坝的经验传进我省,用水坠法筑坝在省内再次兴起,各地陆续采用水坠法修建了一批中小型土坝。据不完全统计,到目前为止,全省用水坠法修建的土坝共60多宗,最大坝高68米,最大库容8,225万立方米。 近年来我省修建的水坠坝,绝大部分都是成功的,积累了一些经验,但也有些工程在施工中出现过位移、裂缝和滑坡等
I. Introduction In the late 1950s and early 1960s, our province successfully built the water fall dam in Gapxia in Jieyang County and Shau Kei Wo in the outskirts of Guangzhou with the method of water fall. At that time, Chong filling dam. In 1975, Shanxi and Jin built the experience of building water fall dam and introduced it into our province. The construction of water fall method dams up again in the province, and a number of small and medium sized earth dams have been constructed by water dropping method. According to incomplete statistics, so far, more than 60 soil dams have been constructed by the water drop method in the province, with the maximum height of 68 meters and the maximum storage capacity of 82.25 million cubic meters. In recent years, the construction of water fall dam in our province has been mostly successful with some accumulated experience. However, some projects have also experienced displacement, cracks and landslides during construction
