张拉区 [zhāng lā qū]
stretched zone
- 研究认为，低地应力区地下洞室围岩压力可分为拱顶横向拉张塌落型、侧壁切向挤压滑落型和洞周自重掉落石块型三种破坏类型产生的围岩压力，并讨论了低地应力区地下洞室围岩压力的计算公式。
The studying results show that three types of surrounding rockmass pressure were put out, they are tension collapse, extrusion press slide types and gravity fall surrounding rockmass pressure, and then calculating formula have been discussed. - 研究表明，在张拉横向预应力钢束以后，主梁边箱斜腹板中部会出现高拉应力区以及混凝土裂缝。
It was showed that under the transverse tension, high stress concentration and even concrete cracks would appear on the oblique webs of the model. - 文摘:中、下扬子区广为发育的前缘逆向倾滑，后缘正向倾滑和两侧为走滑断裂所限的薄皮层块构造，系挤压和拉张作用处于同一运动系统中，是由岩石的物质分层、能量分层和构造分层作用及层滑运动所致。
Abstract: The thin-skinned layer-block structures confined by the reverse dip-slip fault in a leading edge,normal dip-slip fault in a back edge and strike-slip faults (lateral sinistral and/or dextral fault)widely developed in the middle-lower Yangtze River area,may result from layering of rock materials and energy,and structures as well as layer sliding.
