Based upon the above causes, taking the Hongmiao colliery"coal bed 5-1 south working face conveyance laneway on Sector 5 of Pit 2"for the project example, it can be known through primordial rock stress test result that Sector 5 of Pit 2 belongs to high-stress area, whereas wall rock is a class V terrane with terribly labilization.

基于上述原因，以红庙矿"二井五采区5-1煤层南一工作面运输巷道"为工程实例，通过原岩应力测定成果可知，二井五采区属于高应力区，围岩属于V类极不稳定岩层。

In combination with the crushed rock slope as an example, the allocation of an anchorage force on longitudinal beams and transverse beams is calculated by adopting the distribution coefficient law of the nodal form at first. Then the internal forces of the lattice beam are calculated respectively through the software on the basis of Winkler elastic foundation model and the semi-infinite foundation model, and then compared with the internal forces which are based on simplified foundation pressure calculation. The active pressure of rock is calculated approximately by Ranking soil pressure theory in the working stage. Sequentially, the reinforcing bars are disposed by two-stage's averagely calculated values.

以破碎岩质边坡为例，采用节点荷载分配法计算了锚索锚固力在格构梁纵、横梁之间的分配比率，然后基于Winkler弹性地基模型和弹性半空间地基模型分别计算格构梁在张拉阶段的内力，并与采用简化的地基反力计算值对比；采用朗肯土压力理论近似计算在工作阶段主动岩体压力，将地梁视为在线性分布力作用下倒置于坡面上的连续梁，按力矩分配法计算地梁内力，取两阶段计算平均值进行配筋。

The observation results reveal the difference between surrounding rock pressures of shallow tunnel calculated by exiting methods and test results is large, pressure figure seems cat ear, surrounding rock pressure of deep tunnel belongs to clastic pressure, the test result is consistent with result by modified KAKE formula, the invert stress properties of shallow tunnel and deep tunnel are different, the axial force of lattice girder is at pressure in majority, and the stress of second lining is relatively small in loess highway tunnel.

实测结果表明：现有浅埋隧道围岩压力公式计算结果与实测结果偏差较大，其分布呈"猫耳朵"形状；深埋隧道围岩压力属形变压力，其实测值与修正卡柯公式计算结果较为一致；深埋与浅埋隧道中仰拱的受力性态有所不同；格栅拱钢筋轴力以受压为主；黄土公路隧道二次衬砌受力相对较小。

I wanna rock, I wanna rock let me get a lil bit of that donkey right.

我要摇滚，我要摇滚，让我得到莉儿一点说，驴子的权利。

By summarizing the futures of the relative permeability curve in low permeable reservoirs and study of the futures of relative permeability curve in lithic arenite which rock fragments are most come from tuff and lava, it is the reservoirs rock character, the type of detrital minerals, the degree of grains coarse and the lay out of clay mineral that are main influencing factors which influence the relative permeability curve.
