【摘要】 在国内外沥青混合料抗剪试验方法研究分析的基础上,提出了一种全新的即同轴剪切试验方法,同轴剪切试验方法不但比较简便,而且试件受力特点符合路面的实际状况.建立同轴剪切试验模型的三维有限元模型,着重对同轴剪切试验试件力学响应进行分析,然后对同轴剪切试验试件受力特点进行有限元分析;根据试件的受力特点提出沥青混合料抗剪强度的指标,采用三轴试验抗剪强度指标进行对比验证.更多还原

【Abstract】 Based on the research of the shear test methods at home and abroad,the paper presents a new shear test method,the coaxial shear test.The method is simple,and the test sample stress characteristic conforms to the actual road conditions.The mechanics responses of the test samples are analyzed by three-dimensional finite element analysis method,and the coefficient of shear strength is then developed.Finally,the triaxial test results are used to confirm that the co-axial shear test results are correct.更多还原
