摘要:
港珠澳大桥沉管隧道采用从东、西人工岛向中间沉放形成合龙口,再沉放最终接头贯通的施工模式,最终接头状态参数测量是决定工程成败的关键因素. 针对贯通测量方法效率低,测量精度差,且无法实时调整合龙口状态等问题,提出合龙口状态形成过程的实时测量方法. 首先,在形成合龙口的两个管节端面上布设测量特征点,并测量获取管节坐标系下的特征点坐标. 其次,在沉放过程中,采用测量塔法和人孔井投点法进行合龙口实时测量及状态调整;沉放结束后,采用传统贯通测量方法测量合龙口状态. 最后,将3种测量结果统一换算到工程坐标系下,利用测量误差传递模型进行精度对比分析,得到沉管隧道施工合龙口状态的最佳测量方法. 该方法改变了国内外沉管隧道施工中先形成合龙口状态,后贯通测量,再精确调整的施工方式,为沉管隧道以及水下管道等大型水下安装工程提供了参考.
Abstract:
The immersed tunnel of the Hong Kong-Zhuhai-Macao Bridge adopts the construction mode of sinking from the east and west artificial islands to the middle to form a closed dragon mouth, and then sinking the final joint through. The final joint state parameter measurement is the key factor determining the success or failure of the project. Aiming at the problems of low efficiency, low measurement accuracy, poor reliability and inability to adjust the state of the closure in real time, this paper proposes a real-time measurement method for the formation of the closure state. Firstly, the measurement feature points are arranged on the end faces of the two pipe joints that form the closure, and the coordinates of the feature points in the pipe joint coordinate system are obtained by measurement. Secondly, in the process of sinking and laying, the measuring tower method and the manhole casting point method are used to measure and adjust the state of the closing mouth. Finally, the three measurement results are uniformly converted into the engineering coordinate system, and the accuracy is compared and analyzed by using the measurement error transfer model, and the best measurement method for the closing state of the immersed tunnel construction is obtained. This method changes the construction method of forming closure first, then measuring through and then adjusting accurately in the construction of immersed tunnels, and provides a reference for large-scale underwater installation projects such as immersed tube tunnels and underwater pipes.
