Study On The Displacement Of The Large Section Shallow Soil Tunnel In The Seasonal Cold Regions During The Construction

This paper researches the displacement of large section soil tunnel in cold regions based on Tian Hengshan high-speed beltway in Harbin.Firstly,The text discusses the principle of the monitoring measurement,request of instrument,designing,data collection and information analysis and so on,relying on the monitoring measuring results;and also get the direct locale data,by real-time monitoring the surface settlement and displacement of the rock.Secondly,using the excel and origin soft to process the data.The text researches the affections and rules of different rock and support systems during construction by statistical methods;studies the rules of displacement of tunnel due to construction.At last,based on the actual engineering,this paper researches the displacement of the tunnel during construction.Based on the above,we get the following conclotions:1,Summarying the rules of the surface settlement of tunnel in cold regions and the evolving characteristics of the surface settlement slot of the the large section shallow soil tunnel in the seasonal cold regions.2,Summarying the rules of the displacement in the internal rock and the displacement of the hole of the large section shallow soil tunnel in the seasonal cold regions.3,Making sure the range of rock,providing useful information to stability of the rock to make sure the safety of construction.By collecting the data,also provides the analogous reference for the same job.
