Analysis indicates that there is little difference in the displacement of tunnel and well control of stratum displacement by both methods. Plastic zone develops more obviously above the tunnel side by CRD method and is larger by CRD method than by dual sidewall guide pit method. It is comparatively obvious that the plasticity district develops in the side direction of the tunnel by dual sidewall guide pit method and the leading influence distance is also longer than that by CRD method. The development speed of plasticity district is comparatively fast in the range of the leading 3~6 m in CRD tunnel and 0~3 m in sidewall guide pit tunnel. There are different advantages by both methods for passing through sand layer.

结果表明，采用这2种工法时引起的隧道变形相差不是很大，都能较好地控制地层的变形；采用CRD法时产生的塑性区较双侧壁法大，且向隧道侧上方发展较为明显；采用双侧壁法时产生的塑性区在隧道侧向发展较为明显，超前影响的距离也大于CRD法；采用CRD法时的塑性区在超前3~6m的范围内发展速度较快；采用双侧壁法时的塑性区在超前0~3 m的范围内发展速度较快；对于隧道穿越砂层而言，2种工法各有优势。

The shaft is the CA6140 one of the important parts, the main role is to pass a belt and pulley transmission power, The main axis of the state to bear moment, torque and deformation and, therefore, prone to fatigue fracture easily transtensional, bending deformation.

而该轴也是CA6140中的重要零件之一，其的主要作用是通过皮带和带轮传递动力，该轴的主要工况是承受弯矩、扭矩和变形等，所以容易疲劳断裂，容易扭断、弯曲变形等。

Beichuan-Yingxiu fault was weakly thrusted in the early stage and was deformed in the late stage. Anxian-Dujiangyan Dam fault was deformed. Thrust plane developed well in the nappe, which was thrusted from NW to SE.

其中，北川－映秀断裂早期以弱韧性逆冲为主，晚期发育浅部的脆性变形，而安县－都江堰断裂为简单的脆性变形，推覆体内部发育大量与推覆作用有关的逆冲断片，总体上呈叠瓦状分布，由北西向南东推覆。

Our study indicates that along the locked thrust fault, vertical uplift is its primary characteristic before the quake.

That means that we take maximum settlement value as an objective value, that is, to control surface settlement is to control pipeline deformation. Its research paths are to make decision of computational method of maximum surface settlement and settlement pattern firstly; then to establish the relationship between maximum surface settlement and ground pipeline deformation and strain, to get maximum surface settlement in term of th

研究思路是：首先要搞清楚地表沉降的规律以及地表最大沉降值的计算方法：然后研究地表最大沉降值W.x与地下管线的变形及应变的关系，从而可以根据管线与隧道的相对位置、地层条件、管线的允许变形情况求出w皿厂这样通过控制地表最大沉降值w删x就可以间接控制隧道工程对地下管线的影响。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
