摘要
Abstract
The high precision immersion and docking is the key part in immersed tube tunnel construction, which requires better environmental adaptation and high accuracy to the measurement system. Now,the high-precision total station and rigid measurement tower are commonly used in actual engineering. Moreover,the sonar method is also proposed in foreign country,which has good adaption to the surrounding and its precision does not decline with the tunnel length increasing. Through innovation and improvement based on the underwater sonar methods,the ultrasonic array measurement system was proposed by the three points resection method and was used to measure and monitor the immersed tube tunnel immersing and docking process of Foshan Fenjiang road extending to the south. Compared with the high-precision total station,the method can meet the needs of engineering,and the 3-axis measurement precision can be controlled between +45 mm and-45 mm when the distance between two tubes is 2 m.关键词
