摘要：
The immersed tube tunnel of Hong Kong-Zhuhai-Macao Bridge is about 6.7 km long and 44 m deep under water. Because of the complexity of the geologic conditions, different ground treatment measures are used in this project, such as SCP and heavy-tamping broken stone piers. The deformation compatibility of ground treated by different methods should be verified before the immersed tube installation. In this paper, a loading test system designed for deep water is recommended. This system was used during the construction of Hong Kong-Macao-Zhuhai Bridge. The settlement of macadam bed in deep water is obtained and the deformation compatibility is verified by this system. Instant settlement is also obtained, which provides the basis for the elevation design of macadam bed. Settlement characters of the load test are the same as the settlement characters of immersed tube tunnel. So the reliability of the test system is verified.
