Abstract:

The tunnel displacement measurement is only a part of the whole displacement curves limited to construction site conditions at present, however, there are little research on the unmeasured part of tunnel rock mass displacement. The measured data of arch crown settlements of the subsea tunnel each part rock mass was analyzed by regression method; so we get the first part of unmeasured displacements in CRD1 part and CRD3 part(Y1) .The whole curves of the subsea tunnel each part rock mass was studied by the finite difference method; and we gain the proportion of the unmeasured displacements in the whole displacements, so we can give the second part of unmeasured displacements in CRD1 part and CRD3 part(Y0), then we know the whole curves is the sum of the measured part(Ym) and the unmeasured part(Y0 and Y1

Key words: subsea tunnel, rock mass, whole curves of displacements
