Analysis on Changes of Mechanical Properties of Lining of Tunnels in Huangtu Regions Taking Account of Loess Cavity by Using ADINA

Abstract:

In this article, we focused on changes of mechanical properties in lining of tunnel caused by loess cavity. We established a corresponding model and carried out numerical analysis by using finite element analysis software ADINA, considered the effect of different locations, different size of the cavity and depth of the tunnel. The results showed that change of the mechanical properties has the largest effect on the lining at the arch foot nearby the loess cavity, and it grows with the growth of the cavity‘s size and depth of the tunnel.
