摘要

某工程边坡深卸荷形成机理的物理模拟试验要求模型材料的重度与原型一致，强度是原型的0.002倍。该材料具有相对较高重度、低强度的特征。如何研制和试配出该特性的相似材料是物理模拟试验成败的关键环节。从材料选择、模具设计、试样制作、配合比试验等方面系统开展了模型相似材料的试验研究，最终获得满足试验要求的材料组成、配比及工艺。该材料由铁粉、重晶石粉、石英砂、松香酒精溶液按规定配比均匀拌合击实而成。材料物理力学参数可调整的范围较大，对于类似研究可通过调整组成材料的含量而达到相应的目标参数。因此，研究不仅为该物理模拟试验提供了技术保证，而且可对类似研究提供借鉴和参考。

Abstract

The unit weight of model material in the physical simulation test on deep unloading formation mechanism of a slope is required to be equal to that of the prototype, and the strength is required to be 0.002 times that of the prototype. The model material is featured by relatively high unit weight and low strength. Developing and designing the required material is the key of the test. We conducted researches in terms of material selecting, mould designing, specimen manufacturing and mix ratio test, and finally obtained the composition, mix ratio and technique of the model material which meets the test requirements. The material is composed of iron powder, barite powder, quartz sand and rosin alcohol solution, which are mixed and compacted uniformly. The physical and mechanical parameters of the material could be adjusted in a large extent, and the content of components could also be adjusted for similar researches to get the corresponding parameters. This research is the technical assurance of the physical simulation test, and in addition, it provides experience for similar studies.
