在填筑坝内埋设测压管,辅以量水圳等设备,以观测分析坝体的渗流变化与裂缝开展情况,对保证水库安全运行,制订蓄水计划,起着重要的作用。务溪水库坝高47.3米,粘土心墙坝,总库容1167万立米,属中型水库。水库大坝浸润线测压管自1965年冬埋设开测以来,已取得了大量数据。但由于反滤设备不够良好,管内污泥淤积严重,再加上人为因素影响,测压管的灵敏度降低,量测范围减少,有的已无法施测。据
In the filling dam buried piezometric tube, supplemented by the amount of water and other equipment to observe and analyze the dam of the seepage changes and crack development, to ensure the safe operation of the reservoir, the development of water storage plan, plays an important role. The water reservoir dam height 47.3 meters, clay core wall dam, the total storage capacity of 11.67 million cubic meters, is a medium-sized reservoir. A large number of data have been obtained since the piezometer for the saturation line of the reservoir dam has been laid since the winter of 1965. However, as the filtration equipment is not good enough and the siltation of the sludge in the pipe is serious, coupled with the influence of man-made factors, the sensitivity of the piezometric pipe is reduced and the measuring range is reduced, and some of the pipes can not be tested. according to
