Abstract

Through studies on the ground surface deformation that the self-walking TBM drills in the ground by climbing. The relevant results show that., the longitudinal settling tank curve over the self-walking TBM track is similar with the settling tank curve that the stochastic medium theory predicts; There is a large deviation between the transverse settling tank curve being formed when self-walking TBM is covered shallowly and the theory of normal distribution; the earth's surface soil is deformation being embedded of the ring resistance structure on some degree.
