摘　　要：海上风能作为一种绿色可再生能源具有广阔的发展前景,对于深海海上风电工程,采用混凝土浮式基础相较传统钢结构基础可以显著增加耐久性,降低维护成本。文章基于浮力提供效率比选设计了一种充气模板结构体系,分析了在充气条件下的力学性能,研究了内部气压、气肋直径、材料厚度对充气模板结构的影响,实现了对充气模板体系的优化。制作了试验样机,验证了采用充气模板实现浮式混凝土基础水上浇筑的可行性。Offshore wind energy,as a kind of green and renewable energy,has broad development prospects.For deep-sea offshore wind power projects,the use of concrete floating foundation can significantly increase durability and reduce maintenance costs compared with traditional steel structure foundation.This paper designs an inflatable template structure system based on the comparison and selection of buoyancy providing efficiency,analyzes the mechanical properties under inflatable conditions,studies the effects of internal air pressure,air rib diameter,and material thickness on the inflatable template structure,and realizes the optimization of inflatable template system.An experimental prototype was made to verify the feasibility of floating concrete foundation pouring over water by using inflatable template.
