石门水库位于陕西省汉中市褒河石门峡谷,大坝为混凝土双曲拱坝,最大坝高88米,坝顶高程620米,弧长260米,坝顶宽5米,最大底宽27.3米。设计正常高水位618米,相应库容1.05亿米~3,有效库容0.64亿米~3。拱坝于1971年3月开始浇筑混凝土,1973年3月基本结束,坝体混凝土约20万米~3。水库蓄水以后,曾对坝体的裂缝及漏水进行过两次检查(上游面因处水下,无法检查)。1974年4月第一次检查时,除发现个别地方渗水外,未发现明显的裂缝。1979年1 Shimen reservoir is located in Hanzhong City, Shaanxi Province Shubei Shimen gorge, the dam is a concrete double curvature arch dam, the maximum height of 88 meters dam, elevation 620 meters, arc length 260 meters, crest width of 5 meters, the maximum width of 27.3 meters. The design of a normal high water level of 618 meters, the corresponding storage capacity of 105 million m 3, effective storage capacity of 64 million m 3. Arch dam in March 1971 began pouring concrete, basically completed in March 1973, dam concrete about 20 million meters ~ 3. After the reservoir was filled with water, cracks and leakage of the dam body were checked twice (because the upstream surface was under water and could not be inspected). At the first inspection in April 1974, no obvious cracks were found except for seepage in some places. 1979
