摘要
應用三向度岩體非線性組成模式以及隧道擠壓變形數值模式,分析新觀音隧道北橫坑工區主隧道北向工作面的擠壓現象,有效模擬節理等不連續面引致隧道圍岩變位的不對稱分佈以及依時性變形行為,並釐清不連續面對隧道擠壓變形的影響。
The influence of discontinuities is studied by numerical stimulation of squeezing behavior of New Guanyin Tunnel in Taiwan. Analysis results indicate that discontinuities dominate the characteristics of deformation and failure patterns of surrounding rock masses of the tunnel. The large long-term deformation during tunneling is studied by considering the strain-softening post-peak behavior and time-dependent mechanical properties of intact rock and joints.
