为探索利用砒砂岩作为筑坝材料的施工方法 ,黄河水利委员会绥德水土保持科学试验站于 1997年进行了试验研究。试验坝采用爆破松动砒砂岩 ,推土机运料上坝及碾压的施工方法。试验结果表明 ,利用砒砂岩筑坝的最优铺料厚度为 40cm ,最优碾压遍数为 3遍
To explore the use of 砒 sand as a dam construction material, the Yellow River Conservancy Commission Suide Soil and Water Conservation Science Experimental Station in 1997 conducted a pilot study. Test dams using blasting loose sandstone, bulldozers transported on the dam and rolling construction methods. The test results show that the optimum paving thickness of dam using 砒 sandstone is 40cm and the optimal number of rolling passes is 3 times
