天荒坪高压渗透试验旨在揭示高压岔管所在岩体在高内水压力作用下的稳定和渗透性,以论证可否建造高压钢筋混凝土岔管,并为设计提供允许水力坡降、渗水量、地应力参数及为工程措施提供依据。3只试验孔的试验结果表明,岔管区域总体上环境地应力足够高,但是,2#岔管附近存在地应力低、渗水量大的局部岩体,需采取工程措施加以改善
The Tianhuangping high pressure infiltration test aims to reveal the stability and permeability of the rock mass where the high-pressure bifurcation pipe is under the effect of high internal water pressure so as to demonstrate whether the high-pressure reinforced concrete bifurcation pipe can be constructed and provide the design permission to allow hydraulic gradient, seepage, Ground stress parameters and provide basis for engineering measures. The test results of three test holes show that the overall environmental stress in the bifurcated pipe is high enough. However, local rock mass with low ground stress and large water seepage near the 2 # bifurcation pipe needs to be improved by engineering measures
