为了填补中国吸力式桶型基础技术专利分析的空白，本文基于相关的专利数据，通过专利文献计量的方法，分析了专利技术的整体发展趋势、专利类型与有效性、技术发展阶段、地域分布、创新主体以及热点领域。分析结果表明：我国吸力式桶型基础的专利技术正处于快速增长阶段，有效专利占比保持较高水平，发明专利占比接近六成，专利申请地区主要集中于沿海各经济发达区域，地域发展以从北向南发展为整体趋势，热点技术领域高度集中。未来我国专利技术发展应注重提高专利质量，均衡地区间发展，完善“产学研”协同发展，扩展技术应用领域，提高技术领域布局合理性。

In order to fill the gap in patent analysis of suction bucket foundation technology in China， this article analyzes the overall development trend， patent types and effectiveness， technology development stages， regional distribution， innovation entities， and hot areas of patent technology by using the method of bibliometrics that based on relevant patent data. The analysis results show that the patent technology of suction bucket foundation in China is in a rapid growth stage， with a high proportion of effective patents and nearly 60% of invention patents. The patent application areas are mainly concentrated in economically developed coastal areas， and the overall trend of regional development is from north to south. The proportion of enterprises among applicants is the highest， and hot technology fields are highly concentrated. In the future， the development of patent technology in China should focus on improving patent quality， balancing regional development， improving the cooperation of industryuniversityacademy， expanding the application fields of technology， and improving the rationality of technology field layout.
