三渡水水库位于五华县郭田公社东部,1969年冬兴建,1971年竣工。最大坝高47米,总库容800万立米。 土坝填筑土料以花岗岩风化残积土为主,含沙量较多。在14米高程以下,坝段施工比较正常,在此高程以上前坡开始抢筑拦洪断面。后坡则分级填筑,虽采用水中填土,但堆填较厚,有的达一米以上,灌水量未掌握一定标准,一般偏少,填筑土料崩解不完善,造成土坝质量较差。 Sandu Reservoir is located in Wuhua County Guo Tian commune east, built in 1969 winter, completed in 1971. The maximum dam height of 47 meters, the total storage capacity of 8 million cubic meters. Earth dam filling materials to granite weathered residual soil, sediment more. Below the 14-meter elevation, the construction of the dam section is normal, and above the elevation the front slope begins to grab the flood-holding section. Back slope grading, although the use of water fill, but the heap thicker, and some up to one meter or more, the amount of irrigation did not grasp a certain standard, generally less than normal, filling soil collapse is not perfect, resulting in the quality of earth dam Poor.
