摘要
阐述了爆破漏斗的破坏机理,并对某厂的水泥砂浆试块进行了无围压时的爆破漏斗实验、单向压力下的爆破漏斗实验和双向等值压力下的爆破漏斗实验。实验结果表明爆破漏斗体积随单向压力增大而增大,随双向等值压力的增大爆破漏斗体积先减小再增大。
The paper illustrates the fracture mechanism of blasting crater. Several tests are conducted for a test sample of cement mortar, including blasting crater test in no confining pressure, blasting crater test under unidirectional pressure, and blasting crater test under bidirectional equivalent pressure done. The test results show that the volume of blasting crater will be increased with the development of unidirectional pressure. And the volume of blasting crater will reduce at first then be enlarged with the development of bidirectional equivalent pressure.
