Researches on excavation deformation caused by cement mixing method outside excavation

During the construction of excavation in soft soils,soil reinforcement outside the excavation is used usually in order to protect the departure and reception of shield and surrounding buildings.Soil reinforcement outside the excavation will improve the strength of soil and affect excavation deformation.Combined with a project example of a metro station in Shanghai,the negative influence induced by excavation deformation caused by cement mixing method outside the excavation was analyzed.Based on the analysis,some measures were put forward in order to reduce the effect of soil reinforcement outside the excavation.These valuable measures are helpful to similar projects.
