- surrounding rock pressure 围岩压力
- the surrounding rock pressure 围岩压力
- It is possible to use Gurit without damaging the surrounding rock. 使用古力特炸药将完全可能不造成对围岩的破坏。
- the surrounding rock pressure of deep soil tunnel can calculate by modified KAKE formula, the surrounding rock pressure of shallow soil tunnel belongs to flexible pressure and pressure figure seems cat ear; 深埋隧道围岩压力可按基于弹塑性理论的卡柯公式计算，浅埋隧道围岩压力属松动压力，分布呈“猫耳朵”形状；
- The effect of the span of cavern, and the water pressure in cavern on stress in surrounding rock is also studied. 随着采深和溶腔跨距的增加，溶腔围岩的压力峰值的大小及峰值点距溶腔边缘的距离也在不断增加，而溶腔的极限跨距则减小。
- The drilling fluid may interact with the surrounding rock in other ways. 钻井液可能会以其它方式与周围的岩石相互作用。
- If the volcano becomes inactive and cools, surrounding rock may be worn away. 如果火山变得不活动并冷却下来，围岩就可能被剥蚀掉。
- Their use made the design of roadway surrounding rock supporting safer. 这些结果的应用使巷道岩石支护的设计更趋于安全。
- Following the enlargement of the dip angle of the rock structure of the pressure of the surrounding rock and the internal force of the lining structure increase all the time. 最后详尽地阐述了在不同岩层倾角状况下，围岩压力与衬砌结构内力分布特征，即围岩压力与衬砌结构受力随岩层倾角的增大而增大。
- The surrounding rock of 9300 drift is of plastic soft type. Because of great ground pressure, rock movement and long action duration, the support facilities were destroyed. 9300平巷由于围岩为塑性软岩体,地压、位移大,且持续时间长,因而巷道支架破坏严重。
- A change within an intrusive igneous rock caused by the assimilation of portions of the surrounding rock. 内变质作用由于周围岩石同化作用而在侵入火成岩内部产生的变化
- Therefore, the influence of shear dilation on the failure face should be considered for determining relaxed pressure of surrounding rock for the shallow bias tunnel. 因此，在确定浅埋偏压隧道围岩松动压力时应该考虑剪胀对破坏面形状的影响。
