Key Technology of Construction Process Control of Guide Frame Platform Suction Bucket Foundation

Abstract

[Introduction] The present, design and construction technology of suction bucket foundation is not mature, and there is lack of the normative guidance documents, the special research on the key technology of the construction process control of the suction bucket was implemented. [Method] Taking an offshore wind farm project as the background, based on the measured data of orientation platform foundations, statistical analysis, data mining, process back in the inversion method and technology was used. [Result] The constitution and function of the complete set of installation equipment of suction bucket foundation and the intelligent and digital control system are described in detail. The control parameters and control standards in the construction process of suction bucket foundation of guide frame platform are discussed. The feasibility analysis and calculation method and parameter value method of suction bucket penetration/jacking are summarized. The key points and control methods of each link in the whole process of suction bucket from penetration to jacking and recovery are put forward. [Conclusion] Finally, according to the measured construction data of seven four-pile guide frame platform suction bucket foundation, the variation characteristics of control parameters and the control effect during the construction of suction bucket foundation are illustrated. It can be used for reference in the design and construction of similar suction bucket platform foundation.
