Ground surface settlement is an important factor to evaluate surrounding rock stability of shallow tunnel. Based on analyzing of the relation between surface settlement monitoring importance and the depth tunnel

determination principles of the settlement standard are discussed. Focusing on the section without neighboring structures

settlement standard of the ground surface is studied considering rock stability

empirical formula and relative codes. The method is applied to Liuyang River tunnel in Wuhan-Guangzhou passenger dedicated line. Results show: urban tunnel’s deformation standard is lower than mountain tunnel’s standard; shallow tunnel’ deformation standard is lower than that deep tunnel’s; the harder the rock is

the lower the deformation standard is; the smaller the tunnel span is

the lower the deformation standard is; the higher the side wall is

the lower the deformation standard is; the main influence factor is the rock’s property

the next is tunnel span
