tension fissure

According to this cognition, the distribution rules of fissure plane were predicted. THE ANALYSIS OF ACOUSTIC WAVE ANOMALY FOR STRESS RELEASE REBOUND TENSION FISSURE PLANE OF DAM FOUNDATION

根据这一认识，作者对裂缝平面的分布规律进行了预测。坝基卸荷回弹张裂面声波异常分析研究

The basic slope failure pattern of tension fissure-circular surface slip-plane failure is obtained for study of slope failure of flat rock strata by use of double bottom friction model by which the difference in strength of various rocks can be reflected.

采用双层底面摩擦模型，研究近水平岩层边坡破坏模式，能体现出不同岩体在强度上的差异，得到近水平岩层边坡破坏为张裂缝圆弧面平面的边坡滑动破坏的基本模式。

Hence, when aa ground fissure or its underlying fault is located in the outer radial tension zone, the movement of ground fissure would be accelerated by groundwater pumping.

当地裂缝及其下伏断层或裂隙位于抽水活动引起的径向拉张应变区域时，地裂缝将出现加速活动；

In the overlying basalt, there is high dip and wide tension fissure zone, which is combined with surface of unconformity which is as basal sliding face, to form loosening rock mass.

在上覆玄武岩层中见有高倾角的宽张裂隙带，与不整合面一起构成松动岩体，不整合面为底滑面。
