| 摘 要： | 随着工程建设的发展,最高压力为1.0 MPa的常规压水测试,已不能满足具有压力洞室工程的勘测需要。只有按照洞壁围岩实际承受的压力进行高压压水测试,才能为确定岩体的高压透水性状、洞壁围岩的临界破裂压力、岩体透水性随时间的变化特征,以及岩体高压作用下的变形与工程稳定性分析等提供可靠依据。

| Abstract: | As the development of underground engineering construction, the water pressure test that the highest pressure is only 1.0 MPa cant meet the engineering demand which possess the pressuring chamber. Only according the bearing pressure of the surrounding rock to carry out the high water pressure test, could get the data such as permeability behavior of the surrounding rock, its fracturing critical strength, the character of variation of permeability with time under the fixed high pressure, and the surrounding rocks strain character. |
