Study on Settlement of Highway Bed due to Underground Construction of Crossing Railway Tunnels
Ground settlement due to construction of underground crossing railway bed is an important issue. In this paper, the influence of the tunnels depths, the elasticity modulus, Poisson’s ratio, and internal friction angle of the sub grade soil property to the ground settlement during construction is simulated by the numerical simulation method. Some conclusions are drawn. Firstly, the tunnels depth doesn’t only influence the growth of the ground settlements, but also the shape of traverse settler. Secondly, the sub grade soil properties mainly affect the larger settlement; the shape of the settlement trough was relatively small.
