This study is based on the groundwater system in Pengshan water resources area,aiming at the problem of ground subsidence in study area,applying the theory of soil mechanics and dynamics of groundwater,the aquifer consolidation model under the condition of exploitation in water resources is established.

Expatiating the merits,mechanics and the key control technology of the injection process,and drawing a conclusion that it′s just an exploring process of injection process in the road basic reinforcement and needs to perfect it continuously in the future construction.
