摘　　要：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Suide Soil and Water Conservation Experimental Station of YRCC conducted tests and study on probing and using the construction method of feldspathic sandstone as dam building material in 1997.The tested dam used the method of demolishing for loosing,materials carried by bulldozers and roller compaction after.It is shown by the tests that the optimized paving thickness of a dam built by using feldspathic sandstone is 40cm and the optimized number of roller compacted times is 3.
