| Abstract: | In the light of Haikou Meilan Airport＇s Tunnel Engineering of Hainan East-ring Railway,this paper proposes the support scheme of replacing the steel support with the tension dispersion-type anchor rope.Through the design and construction and site monitoring of tension dispersion-type anchor rope,people can grasp timely the changes of axial force of pre-stressed anchor and the influences of these changes on the foundation pit support structure and construction safety.Anchor rope＇s loading and unloading tests and monitoring data show that the tension dispersion-type anchor rope has obvious effects on strengthening the safety and reliability of engineering. |
