苏联和国外建筑土坝时,日益广泛地采用抗压强度不小于15兆帕(即153公斤/厘米~2)的低强度岩石,来自残积层——坡积层——洪积层的天然破碎的岩石,例如:粉砂岩、泥板岩、含粘土的页岩,粉状自云石、白垩等,均属于这类岩石之列。苏联萨戈尔斯克水库大坝已经采用了强风化的粉砂岩和泥页岩;中乌拉尔选矿联合企业尾库坝体用的是采矿场剥离的土料,它们从坚固的岩石到砂质粘土,以不同风化程度的辉岩为主。在克里米亚的萨毕引斯克坝及施阿河的大坝都是众所周知的利用低强度岩石的实例。一些国外的坝也有用这种土料的,如葡萄牙的密尔坝;美国的别衣尔、斯柯特日斯喀、盖
During the construction of earth-mounds in the Soviet Union and abroad, the use of low-intensity rock with compressive strength of not less than 15 MPa (ie 153 kg / cm 2) is increasingly widespread, natural disintegration from the stratum-slope-deluge Such as siltstone, mud slate, clayey shale, powdered dolomite, chalk, etc., belong to this group of rocks. Strongly weathered silt and shale have been used in the Sagogske reservoir dam in the Soviet Union; tailings dam bodies in the Ural mineral processing complex have been decontaminated from mining sites, from strong rocks to sandy clays, The degree of weathered rock is the main. The Sapirinsk Dam in the Crimea and the dam in the Shia River are all well-known examples of the use of low-intensity rocks. Some foreign dams are also useful for this type of material, such as Milwaukee in Portugal; Doyler in the United States, Scott Ritka,
