| 摘 要： | 目前施工井筒检查孔时,不进行浸水试验、RQD值的测定.本文认为:在施工井筒检查孔时,就必须正确鉴定岩芯,进行浸水试验,计算RQD值及测试岩石单轴抗压强度值.应用这四种参数在井筒开凿前,正确评价围岩稳定性,为井筒设计、预算、施工提供依据.

| Abstract: | examination holes of shafts are undev construction, immersion tests and measurement of RQD value are not generally made presently but the author thinks that it is necessary to determine the core correctly, make immersion test, calculate RQD value ,and test compression strength for rock. Stability of surrounding rock can be evaluated correctly by four kinds of paramters before excavating shafe,which provides the scientific basis for the design, investment prediction and operation of shaft. |
