这支巡逻队刚走过钟面街下面的弯曲巷道和三条死胡同。
This patrol had just visited the curving gallery and the three blind alleys which lie beneath the Rue du Cadran.
此举既避免了上下山掘进过程中,巷道变形挤压容易造成横梁弯曲,还延长了提升机的寿命周期。
This not only avoids the park tunneling process, the tunnel deformation caused by squeezing the beam bending easily, but also extend the life cycle of the hoist.
岩石较少有直接拉伸破坏,在巷道和采场顶板中,弯曲变形是重要的变形模式。
The bending deformation was a kind of important deformation mode in the tunnels and roofs of coal mines because direct tensile failure of rock seldom happened.
