Study on Underground Utilities Settlement during the Construction of Shield Tunnel

Abstract:

Shield tunneling construction inevitably makes impacts on underground utilities. This paper takes some Metro engineering for background, study the underground utilities settlement rules induced by shield tunneling construction. As for shallow-buried and high ground water table tunnel, the coupling of hydrological and stress field must be paid attention. By seepage continuity equation and hydrodynamic equations, study changing situation of the deformation and stress by contrast the effect of seepage. And, contrast the measured value and simulation value to verify the rationality of using fluid-solid coupling method to forecast the ground settlement during tunnel construction.
