| 摘 要： | 岩石弯曲拉伸强度和变形性质是确定岩体力学特性的重要参数。为此,该文对32件砂岩、大理岩、花岗岩岩石试件进行了三点弯曲拉伸试验,获取其抗拉强度,绘制了岩石拉伸应力-应变曲线,给出了拉伸弹性模量。通过此次试验研究,并与其它试验进行比较分析,认为岩石弯曲拉伸试验可获得合理的力学参数,且在岩体工程中具有应用前景。

| Abstract: | 32 samples including sandstone, marble and granite were tested to obtain bending tensile strength in the paper. Stress-strain curves of rock tension and tensile elastic modulus are obtained based on the tests. Comparing the result of 3-point tensile tests with other test methods, it is concluded that the test is successful as a test method of character of rock mechanics. The method will have practical application in the future. |
