高速公路隧道施工测量技术研究

Research on Measurement Technology of Expressway Tunnel Construction

高速公路隧道工程往往面临着十分复杂的环境,对技术要求较高,同时不确定影响因素也较多,如果没有充分做好各项工作,很容易发生不可预知的危险事故。为确保高速公路隧道工程施工质量,需要做好工程规划、勘测、施工、运营等各个环节的测量工作。本文结合高速公路隧道工程实际情况,探讨了隧道施工测量技术的要点,研究表明隧道的标高、中线、净空、预留沉降及限界是施工测量的关键参数,需要及时反馈测量结果,为隧道施工提供可靠依据。

Expressway tunnel engineering is often faced with a very complex environment,with high technical requirements and many uncertain influencing factors.Unpredictable dangerous accidents are likely to occur if all work is not done well.In order to ensure the construction quality of expressway tunnel engineering,it is necessary to perform good measurements of engineering planning,survey,construction,operation and other links.Based on the actual situation of highway tunnel engineering,this paper discusses the main points of tunnel construction measurement technology.The research shows that the scale height,center line,clearance,reserved settlement and gauge are the key parameters of construction measurement,and the measurement results should be reported in time to provide reliable basis for tunnel construction.
