| 摘 要： | 自然界中广泛分布粗粒土，其具有压实密度大、良好透水性、抗剪强度高、沉降变形小、不易产生地震液化等优良的工程特性，已被广泛运用于土石坝工程建设中。本文在阅读大量参考文献的基础上概括和总结了粗粒土大三轴试验研究进展情况，包括抗剪强度、变形特性、应力-应变关系特性、试验中的若干问题，并结合已有认识，提出了笔者一些自己的思考，指出了今后关于粗粒土的研究方向。

| Abstract: | Coarse-grained soils are widely distributed in nature. They have a good compaction performance, including high density, strong water permeability, high shear strength, small settlement. They are not easy to produce liquefaction under the earthquake load. They have been widely used in earth dam construction. On the basis of reviewing a large number of related publications, some advances of the research on the coarse-grained soils are summarized in this paper. They include the shear strength, the deformation behaviors, the stress-strain relationship characteristics and several problems in test. The authors presents some of their own thinking, pointing out the direction of future research on the coarse-grained soils according to the existing knowledge. |
