| 中文摘要: |
| 隧道施工会引起周围土体移动。进而对邻近建筑物产生危害。建立隧道从砌体结构正下方和右下方穿越的三维有限元模型．分析地表在隧道开挖和既有砌体结构共同作用下的位移变化规律、砌体结构变形及损害程度。结果表明：砌体结构的自重会显著增大地表沉降值及其范围，其刚度会减小地表的差异沉降，门窗及拐角处由于应力集中发生较大剪应变，砌体的最大剪应变决定于相对位移。隧道从砌体右下方穿越引起的砌体损害程度较大。 |

| The tunnel excavation generates soil settlement around the structure,and causes the structure to deform and even damage. Numerical modeling of tunneling goes through underside the masonry structure is established. The combined effect of tunneling and structures on ground movement is analyzed,and the deformation and degree of damage influenced by tunnelconstruction are studied. The results show that the settlement and its area of the ground increase significantly due to the weight of structure,but the relati... |
