| Abstract: | Because foundation trench excavation is the key process of immersed tube tunnel construction,its real-time monitoring is very important.Using GPS technology,underwater sonar technology and their comprehensive analysis,the underwater quality detections of foundation trench in Guangzhou Luntou-Shengwudao tunnel project have been made for different working conditions(such as before the excavation,after formation in early digging,after the meticulous digging and before tube sinking),and then the status of const... |
