Strata displacement in roadbed caused by shallow pipe jacking construction

In municipal engineering, as a trenchless method, pipe jacking has such advantages as environment friendliness, no interruption to traffic and no effect to people's daily life. Combined with an actual project, the strata's displacement caused by shallow pipe jacking crossing roadbed is simulated with finite element method, by which the effect region of shallow roadbed stratum displacing by shallow pipe jacking is identified. After the comparison, the finite simulation result and on-site measuring data matches which proves the feasibility of applying the finite element model to actual project. © 2015 ejge.
