渗流对高崖头隧道围岩稳定性影响的数值模拟研究
Numerical simulation on the effects of seepage on stability for high cliff tunnel
摘要
Abstract
In the process of tunnel excavation, the groundwater seepage has greater impact on the stability of wall rock. According to the circumstances of the high cliff tunnel in highway from Luoyang to Luanchuan, the paper applied the finite difference software FLAC3D, established the three-dimensional model,researched the displacement of wall rock when considered the seepage or not considered the seepage, and compared with the value of field monitoring data. Analyzed the stability of surrounding wall rock by using the results of numerical simulation. The results shown that the crown settlement and peripheral displacement in considering the role of seepage were more than the case without considering the seepage, and more closely with the value of field monitoring value, tunnel was in a stable state. The research results have a certain role in guiding practice.关键词
