摘要
岩石点荷载强度试验可以求得岩石点荷载强度指数,由强度指数与抗压强度之间的关系可以换算出岩石的单轴抗压强度。该文通过点荷载试验实例,介绍了点荷载试验机理、以及具体的试验步骤,并得出岩石抗压强度,在一定程度上验证了有关点荷载试验公式的可靠性。
Point load strength index of rock can be determined by point load test,and with the relation between index of strength and compression strength.monoaxial compression strength is worked out.In this paper theory of point load test and detailed steps of test are got through point load test.finally.the reliability of formulas concerned about point load test is validated by the result of the test to some extent.
