摘要
针对深中通道沉管隧道合龙口长度评估问题,对隧道长度测量精度进行分析,并对合龙口里程进行预测.通过分析洞内导线贯通测量精度、测量塔投点测量精度以及管节长度偏差等因素,评估了隧道长度测量的可靠性.同时,结合实测数据,对合龙口里程进行了预测,为最终接头制作配切提供参考数据.
Abstract
Aiming at the problem of evaluating the closure gap length of the immersed tube tunnel in the Shenzhen-Zhongshan Link,the measuring accuracy of tunnel length was analyzed,and the mileage of closure gap was predicted.The reliability of tunnel length measurement was evaluated by analyzing the factors such as the accuracy of in-hole guide wire breakthrough survey,the accuracy of measurement tower casting point survey,and segment length deviation.Meanwhile,combining measured data,the mileage of the closure gap was predicted,which provides reference data for the preparation of the final joint cutting.
