| 摘 要： | 介绍了二郎山公路隧道轴线上3个钻孔的地应力测试结果，应用水压致裂法在钻孔中测试，所测的两个不同大小的水平主应力都大于垂直主应力（除了地表以下很浅处外），这个地应力与区域大地构造方向一致，在此基础上评价了隧道碉室围岩的稳定性。

| Abstract: | This paper introduces the measuring results of ground stresses of 3 holes in the road tunnel axis of Erlang mountain with hydraulic fractured method. The two major horizontal stresses are bigger than vertical stresses (expect the shallow under the earth surface). The directional coincidence of ground stress and geotectonic is discussed,and surrounding rock stability of chamber in the tunnels is evaluated |
