近年以来,从各方面的情况都表明堆石料是建高土石坝的最经济的材料。其方量约占整个坝体堆料的三分之二以上。为了进一步研究堆石料的强度和变形特性,需要采用大型试验设备。作一次大型堆石料试验,要耗费很多人力和时间,而建立这样一套设备费用很大。因此,只有多数国家如美国、墨西哥、日本、及意大利等国有这样的设备。有关堆石料的研究 In recent years, from all aspects of the situation have shown that rockfill is the most economical material for building high earth-rockfill dam. The amount of square about the entire dam stack more than two-thirds. In order to further study the strength and deformation characteristics of rockfill, large test equipment is needed. For a large rockfill test, it takes a lot of manpower and time, and the establishment of such a set of equipment costs a lot. Therefore, most countries such as the United States, Mexico, Japan, and Italy have such equipment. Research on rockfill
