海上工程吸力筒导管架基础沉贯理论与实证分析研究OA北大核心CSTPCD

To verify the consistency between theoretical calculation of American Petroleum Institute(API)specifications and authentic test data on site,as well as the effectiveness of new leveling tech-niques,taking the three suction bucket jacket foundation of Datang Dalian city Zhuanghe offshore wind power site Ⅰ(100 MW)offshore wind power project as the research object,applies static balance method and UC analysis of API specifications,SACS and ANSYS finite element analysis method and so on,to conduct a series of mechanical analyses about soil plug,mechanical analysis on penetration feasibility,penetration UC,vertical bearing capacity and lifting adaptability of suction bucket jacket,by comparing and analyzing actual monitoring data of soil plug height,negative pressure,bearing capacity and buck-ling deformation during the penetration process of suction type three tube jacket are with theoretical cal-culation results,Verified the good fit between theoretical calculation of API specifications and authentic test data on site.At the same time application of two new technologies about"differential positioning of water satellite station+attitude monitoring and orientation measurement+wireless bridge communica-tion combination"and"intelligent control system of suction tube suction penetration equipment integra-tion system",successfully achieved the realization of the functionality of suction bucket jacket founda-tion,the research has verified accuracy of API specification theoretical analysis and the effectiveness of new leveling techniques.At the same time innovative foundation structure of suction bucket jacket of this research can greatly save steel,which can significantly reduce investment cost t of offshore wind power projects,and has high economic value,it is expected to become one of the main foundation types of offshore wind power projects in the future.
