我县位于庐山脚下,北滨长江,南靠庐山,是一个既怕干旱又怕洪水的地方,大小水库、江堤湖堤都比较多。如何搞好水库、圩堤的除险保安,是当前水利战线上的一项主要任务。历年来,我们对一些险库、险堤进行了一些处理,收到了一定的效果,现将两则处理土坝渗漏的实例介绍如下。马头水库是一座中型水库,为均质土坝。按原设计32米坝高填筑坝脚,当坝身填筑到5.5米高时,坝高改为按24.4米填筑,因而,外坝脚留出了一个三十五米宽的平台,原设计坝脚的棱体反滤已起不到滤水作用。一九七五年八月,当水库蓄水位达20米时,
My county is located at the foot of the Lushan, north coast of the Yangtze River, south of Lushan, is a fear of drought and afraid of flooding, the size of reservoirs, embankments are more embankments. How to do a good job of eliminating dangers of reservoirs and levee banks is one of the major tasks in the current water front. Over the years, we have carried out some treatment on some dangerous reservoirs and embankments and received some results. The following two examples of earth leakage treatment are as follows. Ma Tau Reservoir is a medium-sized reservoir, a homogeneous earth dam. According to the original design dam height of 32 meters filling dam feet, when the dam fill to 5.5 meters high, the dam height to fill 24.4 meters, leaving the foot of the outer dam left a 35-meter-wide platform, Prism design of the original foot of the prism filter has not played the role of water filtration. In August 1975, when the reservoir water level reached 20 meters,
