小海子水库始建于1958年10月,1961年开始蓄水,1964年至1984年经两次扩建,水库库容达到5亿立方米,设计水位高程1115.50米,水库水面积146平方公里,南坝长11.8公里,北坝长13.2公里,坝顶宽6米,南北坝高均为1117.08米,南北闸总泄水量为490m3/s。本水库任务为下游70万亩耕地及十余万人饮水提供服务。本文对其坝体定喷墙处理作了简单的介绍,其经验值得在50—80年代修建的水库的除险加固来借鉴。
Xiaolizi Reservoir was built in October 1958 and began to store water in 1961. After two expansion from 1964 to 1984, the reservoir capacity reached 500 million cubic meters. The design water level elevation was 1115.50 meters and the reservoir water area was 146 square kilometers. 11.8 km long, 13.2 km long north dam, crest width of 6 meters, north and south dam height are 1117.08 meters, total discharge of North and South Gate of 490m3 / s. The reservoir task for the downstream 70 million mu of arable land and more than ten million people drinking water to provide services. This paper gives a brief introduction to the treatment of fixed dam spraying wall, and its experience deserves reference in the reinforcement of reservoirs constructed in 1950s-1980s.
