摘　　要：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。High pressure permeability test in a drillhole at Tianhuangping was carried out as feasibility studies for manifolds with no steel lining. The maximum testing pressure was 10MPa. Test results show that the average initial stresses in the rock are great enough to build a manifold with no steel linig. But in some places, the stresses are not great enough and the leakage through the surrounding rock mass is rather great. So proper measures should be taken to improve the situation.
