undercrossing的參考例句
1.Undercrossing tunnels are frequently constructed by the shield-driven method in metro projects. Shield tunneling affects the existing tunnel inevitably. 在地鐵工程中，常採用盾構法修建正交下穿隧道，新隧道的掘進不可避免地對既有隧道產生影響。
2.The underground diaphragm wall in Yellow River Undercrossing Project of the Middle Route in the South-to-North Water Diversion is the deepest and thickest one in China. 南水北調中線穿黃工程地下連續牆是國內最深最厚的地下連續牆，地質條件差，施工難度大，施工中存在較大的風險。
3.By means of 3D-FEM, the process of undercrossing shield tunnel construction is simulated and the changing laws of displacement, deformation and internal forces of the existing tunnel are analyzed. 採用三維有限元方法對正交下穿盾構隧道施工進行模擬，分析新隧道動態掘進時既有隧道位移、變形和內力的變化規律。
