Based on measured data of compressive deformation of the strata a FEM Cambridge model is used to study strata consolidation.

In the construction of the underground pavement-Wuhan Qingnian Road(the west Beihu road),the well-precipitation is adopted to evaculate the penetrating water in the pavement field and the up level stagnation water,which consolidates the ground and lays a working condition without water.

Combined with practical engineering,the author introduces the construction scheme of strengthening stratum combining surface grouting with lead small pipe grouting in tunnel,illustrates its construction technology,and shows by engineering practices that this construction scheme has well construction effect,in order to ensure tunnel construction smoothly crossing shallow section.
