当侧规底部扇形不活矮于铁不活立体时，不推纸压球压下去此后，纸弛不离会出不隐凹下下去不隐象，矮速机的不推条也会出不隐同样的障碍，因为扇形不活底下的支点是公道小轴，在校侧时，可以不兵公道小轴的凸背回旋一些，调度到扇形不活背同铁不活立体不等为最好状况，矮速机的不推条是由二块凹形铁撑持，可以不兵凹形铁拆上去，用刨床刨去一些，刨去的厚度即是不推条矮于铁不活立体的间隔，安设此后再举不静调度。

In this study, a commercial CAD/CAM Software is used to plan and generate the multi-axis tool path, and a table rotating/tilting type five-axis machining center is used to perform the experimental machining operation. The material of the die studied is NAK 80 die tool steel, and the geometries are modeled as concave and convex spherical surfaces. Milling parameters considered are spindle speed, feed rate, and different types of cutting tool path. The experimental results show that the surface roughness for concave spherical surface is about 0.247 μm and roundness is about 0.0283 mm and the surface roughness for convex spherical surface is about 0.250 μm and spherical roundness is about 0.0551 mm under the cutting conditions mentioned in this study.

Based on statistical analysis of disced rock cores and rockburst about rock mass in exploration adit at the dam site where high ground stressis surrounded the causes of high ground stress are discussed in many respects, combined with characteristics of ground stress field, including the power source condition which is the regional tectonic setting and geological conditions, power storage conditions which is characteristic of lithology and structure of rock mass, power transformation and adjustment which is late reformation of rock mass. It is considered that high ground stress release is synthetical result caused by factors mentioned above.

针对坝区特定的高应力条件下岩体的应力释放现象，包括岩芯饼裂和勘探平硐岩爆发育普遍的特征，在统计分析的基础上，从力源条件-区域构造背景和地质构造条件、能力存储条件-岩性特征和岩体结构条件、后期演化-能量释放、转换与调整等分析的基础上，结合坝区地应力场分布的特征阐述了坝址区高地应力成因，认为坝区高地应力释放现象是上述各因素综合作用的结果。

At length I spy'd a little Cove on the right Shore of the Creek, to which with great Pain and Difficulty I guided my Raft, and at last got so near, as that, reaching Ground with my Oar, I could thrust her directly in, but here I had like to have dipt all my Cargo in the Sea again; for that Shore lying pretty steep, that is to say sloping, there was no Place to land, but where one End of my Float, if it run on Shore, would lie so high, and the other sink lower as before, that it would endanger my Cargo again: All that I could do, was to wait 'till the Tide was at highest, keeping the Raft with my Oar like an Anchor to hold the Side of it fast to the Shore, near a flat Piece of Ground, which I expected the Water would flow over; and so it did: As soon as I found Water enough, for my Raft drew about a Foot of Water, I thrust her on upon that flat Piece of Ground, and there fasten'd or mor'd her by sticking my two broken Oars into the Ground; one on one Side near one End, and one on the other Side near the other End; and thus I lay 'till the Water ebb'd away, and left my Raft and all my Cargo safe on Shore.

最后，我终于在小河的右岸发现一个小湾。我费尽艰辛，好不容易把木排驶到最浅的地方。我用桨抵住河底，尽力把木排撑进去。可是，在这里，我几乎又一次险些把货物全都倒翻在水里。这一带河岸又陡又直，找不到可以登岸的地方。如果木排一头搁浅在岸上，另一头必定会像前次那样向下倾斜，结果货物又有滑向水里的危险。这时，我只好用桨作锚，把木排一边固定在一片靠近河岸的平坦的沙滩上，以等待潮水涨高，漫过沙滩再说。后来，潮水果然继续上涨，漫上沙滩，等水涨得够高了，我就把木排撑过去，因为木排吃水有一尺多深。到了那儿，我用两支断桨插入沙滩里，前后各一支，把木排停泊好，单等潮水退去，就可把木排和货物品平安安地留在岸上了。

The deformation and failure model of tunnel induced by ground fissure is tensile failure, and tunnel cracks mainly appear in the footwall of ground fissure, but tunnel located in the hanging wall is basically good, which is just adverse to that the damage of buildings or structures on the ground surface caused by the ground fissure mainly in the hanging wall.

地裂缝作用下隧道变形破坏模式为拉张破坏，且隧道衬砌开裂主要出现在下盘距地裂缝14.0 m范围内，而位于上盘的隧道衬砌基本完好，这与地裂缝活动引起土体和地表建筑物的变形破坏主要发生在上盘刚好相反。
