龙须带大坝座落在我省北江二级支流黄洞河上.坝型采用粘土斜心墙土石混合坝.大坝平面布置见图1.计算断面最大坝高68米,顶宽8米.上游坝坡为1:2.5,1:3.0,1:3.5;下游坝坡为1:2.0,1:1.6,1:1.6,1:1.6.大坝以粘土斜心墙为防渗体,其顶宽5米,底宽37米.斜心墙上游坡为1:0.9,下游坡为1:0.4.坝体填土区与坝基接触部位设有粘土铺盖,平均厚度为十分之一水头、约6米,长度为两倍水头、约120米.斜心墙上游填土区土料选用泥岩砾质风化土,坝体下游由56米高的堆石体支撑,斜心墙与堆石体之间布置了泥岩砾质风化土的过渡区及四组级配的反滤体,见图4.
Longshen dam is located in the Yellow River tributary of the Beijiang tributary of our province .Changxing use of clay slope of the wall of rock and soil mixed dam. Dam layout is shown in Figure 1. The maximum section height of 68 meters, the top width of 8 meters. The upstream dam slope is 1: 2.5, 1: 3.0 and 1: 3.5. The downstream slope is 1: 2.0, 1.6: 1.6, 1.6: 1.6 and 1.6: Width of 5 meters, bottom width of 37 meters .Climatic wall upstream slope of 1: 0.9, the downstream slope of 1: 0.4. Dam body fill area and the contact area of the dam with clay cover, the average thickness of one tenth of the head, about 6 meters, twice the length of the head, about 120 meters.Cloving wall fill material selection mudstone gravelly soil, downstream of the dam by 56 meters high rockfill body, oblique wall and rockfill Between the transitional zone of mudstone gravelly weathered soil and the four groups of anti-filtration bodies are arranged, as shown in Figure 4.
