一、基本情况 宝鸡市现有水库128座,其中大中型水库4座,小(一)型水库33座,小(二)型水库91座。百分之九十的水库建于60年代末70年代初,多系“三边”工程,质量差,留有隐患,多年运用后,一些坝体出现裂缝,迎水面塌坑,坝后不同程度的渗漏,水库长期低水位运行,效益不能发挥。1992年普查评定出三类水库达73座,占60.7％,其中小(一)型水库17座。曾用充填式灌浆、黄土铺盖、塑料薄膜防渗等工程措施处理坝体裂缝、渗漏 I. Basic Conditions There are 128 reservoirs in Baoji, including 4 large and medium-sized reservoirs, 33 small reservoirs and 91 small reservoirs. Ninety percent of the reservoirs were built in the late 1960s and early 1970s, with multiple departments of the “three sides” project, with poor quality and hidden dangers. After years of use, some dam bodies have cracks, facing water-level collapses and varying degrees Leakage, long-term low-water reservoir operation, the effectiveness can not play. In the 1992 census, 73 reservoirs of three types were assessed, accounting for 60.7% of the total, of which 17 were small reservoirs. Have used filling grouting, loess bedding, plastic film impermeable engineering measures such as dam cracks, leakage
