岩石材料力学相似性定量评价方法研究
Research of quantitative assessment methods on mechanical similarity of rock similar material
摘要
Abstract
Similar material is one of the key factors in physical model experiment. Two quantitative assessment methods were analyzed. A quantitative assessment method for the mechanical similarity of rock similar material was proposed based on stress-strain curve, which is composed of stress-strain curve assessment, stress-strain curve basedπassessment and compre-hensive assessment. The comprehensive assessment value indicates the level of similarity. The analysis results show that the assessment should contain two aspects. One is the evaluation of discrepancy between theoretical parameters and practical pa-rameters of similar materials, the other is the measurement of the difference in non-dimensional number. The application of this method in integrated physical simulation of tectonic deformation and hydrocarbon charging shows its practicability.关键词
