摘要
为了确定岩体在不同压力作用下渗透特性的变化规律,陕西镇安抽水蓄能电站高压岔管、厂房端墙部位的岩体,专门做了钻孔高压压水试验。通过试验,取得了高压水头条件下岩体的透水性及透水规律,为设计在岔管和地下厂房洞室围岩稳定性、渗透性,制定厂房开挖支护措施和防渗措施,提供可靠依据。
In order to determine rock mass under different pressure on permeability characteristics, the high pressure bifurcated pipe with Zhen＇ an pumped storage power station of Shannxi, the rock mass of workshop end wall have special high water pressure test. Based on the experimental results, the paper obtained the high water pressure in the process of the rock permeability rate of Lu and P-Q curve. To design the bifucated pipe and stability ＆ permeability of surrounding rock of underground powerhouse cavern, the paper formulates support measures and anti-seepage control measures, provides a reliable basis.
