堆积体是一种非均质的岩土材料，与岩(土)体相比，构成堆积体的物质成分变异性很大，且空间结构较为复杂，目前对其力学参数试验研究尚缺乏成熟的理论与技术。以梨园水电站工程区大型堆积体为例，在现场大型试验的基础上，对该堆积体的强度特征及岩土力学特性进行研究和探讨，并经工程地质分析确定堆积体岩土物理力学参数。研究表明，堆积体在天然状态下表现出完整的剪应力-剪切位移曲线，具有较高的抗剪强度。研究成果为堆积体稳定分析打下基础，也为类似工程建设提供相关经验。

Soil-rock mixture(S-RM) is a kind of inhomogeneous geometrical,compared with rock mass or soil , it has variability of material composition , and more complicated space structure , up to now the experimental study of its mechanical parameters are lack of mature theory and technology. Taking a large soil-rock mixture in Liyuan hydropower project area as an example and on the basis of a large in-situ experiments,its characteristics of strength and mechanics are discussed,physico-mechanical parameters are determined by engineering geological are analyzed as well. Researched results show that it has complete shear stress to shear displacement curve and high shear strength in the natural state,it is not only to lay a foundation for stability analysis of soil-rock mixture , but also to provide relevant experience for similar project construction.
