查询词典 shield

This study collects 198 sets of field measurement data due to shield tunneling cases reported in different parts of the world from 1980 to 2008. A hyperbolic model is proposed to simulate the surface settlement-time relationship due to shield tunneling constructed in different types of soils with different shields.

本研究搜集自1980年至2008年间，世界各国共198笔潜盾隧道施工案例之监测资料，利用双曲线模式模拟於不同性质土层内、以不同型式之潜盾机施工引致之地表沉陷历时曲线。

Results show that gas release in gassy sand will cause the additive deformation of tunnel and additive stress of the shield segment, and make important impacts on the global displacement of tunnel but little influences on the stress of shield segments and the relative displacement of tunnel. It is inclined to arouse the differential settlement and cracks on the tunnel so as to cause hazardousness. Re-accumulating of the gas can also produce additional stress and the additive resilience, but it can be ignored in practical engineering because the influence degree is small. The shallow gas in reservoirs is appropriate to be discharged before construction of the subway tunnel.

研究结果表明：气体释放将引起隧道产生附加变形和管片附加应力，浅层气体释放对地铁隧道结构应力和结构相对变形影响较小，而对隧道整体位移影响较大，易引起不均匀沉降，导致隧道裂缝或断裂，进而引发危险；气体重新回聚时，隧道产生的附加应力和回弹位移量较小，工程中可不予考虑；地铁隧道施工前，宜对浅层气体进行预先排放。

In order to reduce the expense production,by using the design principle such as locally supllying strength and approximately equi-strength ,standing shield hydraulic support can be revamped as efficieatly shield hydraulic support.

为了降低生产成本，采用局部补强、近似等强度的设计原理，将支撑掩护式支架改造成掩护式支架，改造后的支架完全具备掩护式液压支架在强度方面和运行轨迹方面的要求，同时也达到了减轻支架自身的目标。

Deiphobus then came close up to Idomeneus to avenge Asius, and took aim at him with a spear, but Idomeneus was on the look-out and avoided it, for he was covered by the round shield he always bore- a shield of oxhide and bronze with two arm-rods on the inside.

其时，德伊福波斯，怀着对阿西俄斯之死的悲痛，逼近伊多墨纽斯，投出闪亮的铜枪，但后者紧盯着他的举动，弯身躲过飞来的枪矛，蹲藏在溜圆的战盾后面――此盾是他常用之物，坚实的牛皮，箍着闪光的铜圈，安着两道套把。

And the inverse result of kinematics for the shield hinge equipment is obtained and one-degree inverse coefficient matrix of the impact, two-degree inverse coefficient matrix of the impact and the expression of velocity, acceleration for every component are calculated, all of these lay the foundation for the following kinetics of the shield hinge equipment.

研究盾构铰接装置的能控性问题，讨论铰接液压缸的驱动力对切口环上末端力的控制能力，通过盾构前体切口环的末端力能控性，理论证明盾构铰接装置在土层中工作时切口环的可行运动与不可行运动，并得到可行运动的运动特性曲线。

There are various ways to shield static magnetic field. The principles of which come to one: to form a relatively closed space by using high magnetic inductivity material, in which space the magnetic flux runs through side of the shield, and thus the magnetic intensity is reduced.

静磁场屏蔽方式可以有许多方法，其原理都是采用高磁导率材料作为屏蔽体材料，在需要屏蔽的空间内形成一个相对密闭的空间，使得磁通沿着屏蔽体侧壁流过，从而减低屏蔽空间内的磁场强度，以达到屏蔽效果。
