The taubate provisional detention center for prisoners awaiting trial near brazil ' s biggest city of sao paulo was opened at the end of 2001 and has already had one publicized escape via an underground tunnel 等候审判的陶贝特临时拘留中心位于巴西最大城市圣保罗附近， 2001年底才启用，但这里已经发生过了一起广为人知的犯人通过地道逃走的事件。
They notice that we re different than them , so they truly can t get along with us . that s why the turtles simply hide in underground tunnels and would rather live in a gloomy place . they can t get along with other people 所以他们就乾脆躲在地下道，宁可住在那种比较黑暗的地方，没办法跟人家合得起来，因为一出去人家会抓他们，会攻击他们，就是这个意思嘛！
There are some disciplinary axial cracks which located in haunch and bottom lining of the underground tunnel during construction period , especially in the third and fourth holes , it is necessary to search for the causes of cracks for preventing and repairing 在浇筑过程中，陆续在各洞体衬砌的腰部附近及底部发现顺水流向规律性很强的轴向裂缝，特别是3 # 、 4 #洞的情况更为严重。因此，有必要探讨裂缝产生的原因。
Continue to go forward at the entrance of an underground tunnel to the ground with their hands on january 1 received props on the walls , four three inserted in charge next four holes , two among four in charge of two insert holes , other tu 继续往前走到地下隧道的入口处，将地上连同手中的道具一一接到墙壁上，其中四个三分管插入上下的四个孔中，两个四分管插入中间的两个孔中，其他的管子做连接用，快速搭好梯子后，爬上。
Based on unified strength theory , the boundary line equation of surrounding rock mass plastic zone under non - uniform stress field was deduced , and it can be used to pre - estimate the dimensions and shapes of underground tunnel ' s plastic zone with different coefficients of horizontal pressure 摘要基于统一强度理论，推导出非均匀应力场的巷道围岩塑性区边界线方程式，可用于预测不同侧压系数时地下深埋隧洞的塑性区大小及形状。
In this paper , based on simulation modeling laws of geometry , constitutive relations , stress conditions and construction , a simulative calculation model has been proposed by considering the mechanical problems during the underground tunnel ' s construction and adopting constitutive models of enveloping type which can consider elasto - plastic materials and their cracking . the model can describe rock multi - media characteristic consider the interrelation of shoring structure and stratum reflect some influencing factors , for example : faultage interlayer joints , construction process and so on 本文结合地下隧洞工程施工过程中的力学问题，基于几何、本构、应力状态和施工过程等四方面仿真建模的原则，采用可以考虑材料弹塑性和开裂的包络型本构模型，建立能描述岩体多介质的特点和能考虑隧洞支护结构与地层的相互作用，同时能反映断层、夹层、节理裂隙以及施工全过程等影响的岩体结构仿真计算模型。
The high island water system had a transport network that included numerous underground tunnels , in total 25 miles long , with diameters of 10 to 13 ft . the main water tunnel was 74 , 000 ft . long ( 14 miles ) , beginning at pak tam chung , near high island , and going through the sai kung peninsula and tai wan to reach the sha tin treatment works 万宜水库的输水网络包括了多条直径10至13尺、共长约25哩的输水隧道，隧道主线长74 , 000尺（ 14哩） ，由万宜水库北潭涌起，横越整个西贡半岛，经西贡大环至沙田滤水厂。
