摘要
监测项目中的测边网通常被用于大型工程,本文结合宁波市常洪隧道沉管接缝的结构特点,将测边网的方法引入隧道狭小的空间中,利用简单的钢尺测量手段,结合拟稳平差方法,成功对隧道沉管结构的相对位移实施了监测,有力保障了隧道的运营安全。
This article uniting the characteristic of the Ningbo Changhong immersed tube tunnel, introduced the mini -trilateration network into tunnel in the narrow space, which used simple ruler measurement methods and imitative stable adjustment. The success of horizontal displacement monitoring for the Ningbo Changhong immersed tube tunnel,powerful safeguard the tunnel operation safety.
