广东省自1958年以来,普遍推广湿法筑坝的方法,其中包括水中填土、土中灌水、层水中填土、层土中灌水以及水力冲填等。关于筑坝土料,除广泛使用含砾风化粘性土外,也使用了半风化砾石土和冲积壤土。几年来,用湿法筑成的土坝达数百座(其中主要由水力冲填建成的5座),最大坝高达57米,坝高40米以上的有7座。实践表明,不同的土料性质对湿法筑坝技术,是有着密切的影响的。
Since 1958, Guangdong Province has generally promoted the wet method of damming, including filling in water, filling in soil, filling in strata, irrigation in strata, and hydraulic filling. For damming materials, semi-weathered gravelly soil and alluvial loam are also used in addition to the widespread use of gravelly weathered clay. In recent years, hundreds of earth dam constructed by wet method (of which 5 are mainly built by hydraulic impulse filling), the maximum dam is up to 57 meters and the dam height is above 40 meters. Practice shows that different soil properties have a close impact on wet dam technology.
