摘要
阐述液化天然气(LNG)储罐地基基础的重要性和复杂性,将储罐地基基础分类归纳为天然地基筏板基础、复合地基筏板基础、低承台桩基础、双承台架空基础、高承台桩基础和双承台架空桩基础六种形式。总结各种基础形式的定义、结构构造及适用范围,并从安全性、经济性、适用性三个方面进行了对比。指出基础的抗震设计和协调变形控制是制约储罐地基基础设计的难点,其理论研究远远落后于工程实践经验。
The importance and complexity of the foundation of liquefied natural gas(LNG) storage tank are briefly described.The storage tank foundation is classified into six types: natural foundation raft foundation, composite foundation raft foundation, low cap pile foundation, double cap overhead foundation, high cap pile foundation and double cap overhead pile foundation. The definition,structure and applicable scope of various foundation forms are listed. The safety, economy and applicability are compared. At the same time, it is pointed out that the seismic design and deformation compatibility control of the foundation are the difficulties in the design of the tank foundation, and the theoretical research is far behind the engineering experience.
