On the puzzle of dynamic simulation of tunnel excavation with centrifuge model, this thesis makes a trial research on the section of SK3+395 of Shenzhen Metro and has made some progress.
并针对动态模拟隧道开挖这一难题利用离心模型对深圳地铁SK3+395断面进行了尝试性的研究，取得了一定的进展。

隧道开挖
The surrounding rock forms the new discharge passage after tunnel excavation, and intensifies the interactions between water and rock.
隧道开挖后形成新的地下水排泄通道,加剧了地下水对岩体的作用。
隧道施工
隧洞开挖
. So it is necessary to study and discuss to tunnel excavation and lining ulteriorly. At first, a elasto-plastic finite element analysis model was applied to simulate the conventional procedure of tunnel excavation and lining with the finite element.
因此,尚有必要对隧洞开挖问题作进一步的研究和讨论。
