白莲河水库大坝为粘土心墙花岗岩石渣组合坝。最大坝高69米,坝底长130米,坝顶长259米。上游平均边坡1:3.01,下游面在一九七五年进行了加坡培厚,增加了背水坡的抗滑稳定。心墙顶高程110.5米,顶宽0.6米,最大底宽16米。大坝横断面见图1。坝址河床基岩为中生代坚硬致密细粒花岗岩,大坝左岸坡度为1:0.9～1:2.5,平均约为1:2;右岸坡度为1:0.5～1:2,平均约为1:1。坝体回填采取一次断流全线上升的方式,于一九五九年十月中旬开工,到一九六○年五
The Bailianhe reservoir dam is a clay core wall granite and gravel combo dam. The maximum height of 69 meters dam, dam 130 meters long, 259 meters long crest. The upstream average slope is 1: 3.01. The downstream face was cultivated in Singapore in 1975, increasing the anti-skid stability of the back slope. Heart wall elevation 110.5 meters, the top width of 0.6 meters, the largest bottom width of 16 meters. Dam cross section see Figure 1. The bedrock of the dam site is Mesozoic hard and dense granite. The left bank slope of the dam is 1: 0.9-1.5: 2.5, with an average of about 1: 2. The right bank slope is 1: 0.5-1: 2, with an average of about 1: 1 . The backfilling of the dam body took a mode of increasing flow across the whole line and started operation in mid-October 1959 to five years in 1960
