Abstract :
Tail void grouting is a key technology of shield tunneling to control stratum settlement. Consolidation deformation process of cemented mortar is determined by cement hydration. Based on experimental results of the influence of cementation on stress-strain relationship and permeability coefficient, the quantitative relations were established. Finally, the consolidation deformation model were derived, it can be used to truly describe the deformation of cemented mortar in tail void.
