| 中文摘要:针对鹰山隧道断面大、跨度大、埋深浅、覆跨比小等特点，设置了５个量测断面，对洞壁水平位移、顶拱垂直位移、地表下沉量等进行了量测，量测结果显示，位移值远小于规定的允许值，为快速、优质、安全施工创造了先决条件。 |

| Abstract: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. |
