| 摘 要： | 本文介绍了新疆吉林台面板堆石坝堆石料的大型振动三轴试验结果，重点研究了堆石料的振动残余变形特性。试验结果表明，堆石体具有相当大的体积收缩特性，如果在堆石坝的地震永久变形中无视这一点，将会带来不可允许的误差。

| Abstract: | The rock materials taken from Jilintai rockfill dam are tested in the large diameter triaxial cell. In this paper the test results are introduced, however, the major attention is focused on the residual deformation of materials under cyclic loading. It is concluded that the rock materials contract considerably under cyclic loading, and this is particularly true for high confining pressure. Therefore, if this behavior is neglected in the analysis of permanent deformation of high rockfill dams, inadmissible error will result. |
