依托港珠澳大桥埋置式承台足尺模型工艺试验项目,采用理论计算分析与原位试验监测相结合的办法对埋置式承台基坑超挖深度进行研究.理论计算分析采用海港水文规范经验公式进行估算,原位试验采用单波束测深仪定期和不定期对试验基坑开挖后水下地形进行测量,在此基础上,提出适宜的承台基坑超挖深度,为港珠澳大桥主体工程建设关键施工参数的确定提供依据.

Relying on the full-scale model test of embedded pile capping for Hong Kong-Zhuhai-Macao Bridge,the method combining theoretical calculation analysis with in-situ monitoring tests is used to study the over-dredged depth of foundation excavation. In the theoretical calculation estimate,an empirical formula of the Hydrology of Sea-port is adopted for the over-dredged depth, while the single-beam is for the topographic survey underwater at random after the foundation excavation in the in-situ monitoring test. On that basis,proper over-dredged depth of pile cap foundation excavation is put forward to provide key construction parameters for the main works of Hong Kong-Zhuhai-Macao Bridge.
