青岗县胜利水库是一座中型水库,均质土坝,最大坝高10.6米,全长2,750米,迎水面为1∶3的沥青渣油混凝土护坡。1983年4月,水库迎水坡遭五次七、八级西南大风袭击,使渣油混凝土护坡原有的冻胀裂缝遭风浪强烈淘涮,许多坝段土颗粒被淘空坡面坍塌。在大坝护坡维修工程中,他们除采取常规颗粒反滤段外,还在200米坝段上,试验应用无
Qinggang Victory Reservoir is a medium-sized reservoir, homogeneous earth dam, the maximum dam height of 10.6 meters, a total length of 2,750 meters, facing the water surface of 1: 3 asphalt residue concrete slope protection. In April 1983, the reservoirs Ying Shui Po was attacked five or seven times in the southwest winds, so that the original frost heaving cracks in the residual oil concrete revetment were strongly shaken by the storms and waves. Many of the soil particles in the dam sections were collapsed by the Amoy skies. In the dam slope maintenance project, in addition to their conventional particulate filter section, but also in the 200-meter dam, the test application no
