Numerical Analysis of Variation Law about Vertical Additional Force of Monolayer Shaft Lining
The shaft lining under the deep alluvium drainage and grouting settlement stratum are in the complex dynamic force state, the stresses of shaft lining have a relation to the consolidation settlement of strata, the transmission coefficient of bottom aquifer and the coupling effect between shaft lining and surrounding soil. To study the variation law about vertical additional force of shaft lining, this paper analyzes reinforced concrete monolayer shaft lining by numerical simulation method, obtaining that vertical additional force of monolayer shaft lining is proportional to the modulus of elasticity of shaft lining concrete and it is proportional logarithm to the transmission coefficient of bottom aquifer, meanwhile, founding that shaft lining’s stress-strain relationship is dynamic when the composite loads are applied and that the plastic zone of shaft lining is resulted from coupling of multiple loads. Therefore, decreasing the transmission coefficient of bottom aquifer and the elasticity modulus of shaft lining concrete is beneficial to reduce the vertical additional force of shaft lining and increases the stability of shaft lining.
