隧道工程施工过程中的力学分析

将施工过程的力学分析方法用于隧道的开挖，对隧道施工过程作三维时空动态模拟，加载体系和研究对象本身构随时间变化，每个时刻的状态为不同时段力学状态时效的逐次叠加．研究结果表明，这一力学分析方法与策略是有效的；并进一步揭示了地下隧道施工过程的力学分析结果与目前通用的完整结构一次性工程计算结果不同的一些新现象．

Construction Mechanics Analysis during the Construction of Tunnel Engineering

In this paper, the construction mechanics is applied to the process of tunnel excavation. In the simulation of the three - dimensional time and space dynamic problem of tunnels excavation, the system of loading and research object is changing along with time. The state of mechanics directly resulted from the construction process is considered as an accumulated state by several sub - states in defferent time steps. The results of this paper indicate that the method of construction mechanics, which is different with the current calculation method, is reliable and efficient.
