| 摘 要： | 隧道设计与施工,查明围岩岩层的透水性十分必要,该深埋隧道勘探工程,根据含水岩层的差异,采取分段抽水试验方法,计算出不同埋深段的岩层渗透系数。设计单位采用该抽水试验结果进行隧道设计,工程施工时实际涌水量与计算值较吻合。该文结合隧道抽水试验对求解渗透系数作了些有益的探讨,供勘察设计单位参考。

| Abstract: | It is necessary to find out hydraulic conductivity of surrounding rock strata for tunnel design and construction.According to the difference of water-bearing rock stratum,sectional pumping testing is adopted,and permeability coefficients are calculated in different burying depth section.The test results indicate the actual discharge is agreed with the calculated value.The solving permeability coefficient combined with tunnel pumping testing are discussed,and it can be used as references for relevant design departments. |
