摘要

巴西圆盘抗拉强度公式是基于弹性力学平面问题解析解，利用最大拉应力准则得到的，但结果与直接拉伸试验得到的强度有较大的差异。根据10种岩石（煤）的直接拉伸试验与弧形劈裂试验数据，分析了弧形加载面积对应圆心角对试样3维应力状态的影响规律，并采用三维抗拉强度准则来分析巴西试样，结果表明此准则更适合于巴西圆盘试验。

Abstract

The formula for the tensile strength of rocks under the Brazilian disc test is based on the plane analytic solution of elastic theory

which is obtained through the principle of maximal tensile stress..But the result is very different from the result of direct tensile test.According the data between direct tensile test and arc splitting test of ten kinds of rocks

the rule of 3-D stress because of central angle of arc loading area is analyzed; and adopting 3-D tensile strength principle to analyze the samples

it turns out that this principle is more suitable to Brazilian test.
