一、前言近年来,由于水电建设发展的需要,土石坝的建设日益向高坝发展。对于高土石坝采用粘土作防渗体,用粗砾料和堆石作为支撑体是一种经济而安全的坝型,往往作为高土石坝的选用坝型。为此粗砾料和堆石的力学性质的研究日渐引起人们的重视,然而,研究粗砾料和堆石料的力学性质需要大型高压力的设备,试验工作量和劳动强度都很大,故目前这方面的试验研究还很不够。
I. Introduction In recent years, due to the needs of hydropower construction and development, the construction of earth-rock dam is increasingly being developed to high dam. For high earth-rock dam clay as seepage prevention body, with coarse gravel and rockfill as a support body is an economical and safe dam type, often as a high dam type of dam. Therefore, the research on the mechanical properties of coarse gravel and rockfill attracts more and more attention. However, the research on the mechanical properties of coarse gravel and rockfill requires large-scale and high-pressure equipment, which requires a lot of work and labor. Therefore, Experimental research in this area is still not enough.
