| 摘 要： | 根据隧道仰坡现场踏勘资料,运用有限元分析软件ABAQUS建立相应的数值模型,结合强度折减法分析隧道边坡的稳定性,计算得出隧道边坡的安全系数为1.022。考虑到岩土参数的离散性和降雨等不利因素,将导致边坡失稳,为此,提出对该隧道仰坡的加固措施,以确保工程安全。

Application of ABAQUS in Stability Analysis of Tunnel Slope at the Portal |
| |
| Abstract: | According to field survey data of an upward slope of tunnel, the finite-element analysis software ABAQUS is used to establish corresponding numerical model. The slope stability is analyzed in combination with strength reduction method. The safety factor of tunnel slope is 1.022 acquired through calculation. Considering various unfavorable factors such as discreteness of geology parameters and rain, the slope may be instable; therefore, measures are put forward for the upward slope of tunnel slope to ensure engineering safety. |
