When shield tunneling passes through special and first level risk projects,it is difficult to achieve settlement control requirements by ignoring the influence of excavation gaps.Mud control effect is a filling mate-rial that can strengthen excavation gaps and reduce shield tunneling friction.This article adopted experimental research and numerical simulation methods to analyze the application effect of clay filling effect in shield tunne-ling construction process,and compared it with actual monitoring data of the project.The results showed that using clay filling effect to fill excavation gaps can effectively reduce soil settlement caused by shield tunneling construction.From this,it can be concluded that the mud control effect is suitable for underpass projects with high settlement control requirements.
