Considering the features of Yingshan Tunnel such as large scale,shallow buried,low overburden spanratio,etc.,five measuring sections are set for measurement of horrizontal displacement of the tunnel walls,verticaldisplacement of the arch and ground surface subsidence.The results indicated displacement values far less than the specifid allowances,crating a prequalification for fast,qualified and safty construction.
