轴向劈裂试验参数对原状黄土抗拉强度的影响分析

The Impact Analysis of Axial Splitting Test Parameters on Tensile Strength of Original Loess

轴向劈裂试验参数对原状黄土抗拉强度影响非常显著,主要来自试验加载速率、试件高度和试验加载圆柱三方面的因素.室内原状黄土劈裂试验结果表明:加载速率过快或过慢得出的试验结果差异明显;一定高度的试件可以有效提高劈裂试验的精确度;加载圆柱的大小直接与测试结果线性相关.

Axial splitting test parameters have great influence on the tensile strength of original loess which is mainly affected by three factors as the loading rate,specimen height and diameter of loading cylinder. The test results indicate that the variation of loading rate can produce significant differences in test results. The specimen with a certain height can effectively improve the accuracy of the split test,and the size of the loaded cylinder is directly related to the test results
