- 摘要:
- 在水下管汇结构中应用筒型基础，具有安装维修简便，安装过程中调平容易，承载能力高，抗海流冲刷、抗地震作用、抗意外碰撞和渔网拖曳、抗水平滑移能力强等优点。文章结合我国首座以筒型基础为支撑的水下管汇结构的海上安装施工，介绍了筒型基础的结构形式、基本工作原理、水下管汇结构形式，总结了筒型基础应用于水下管汇结构的优点，为后续水下管汇结构的设计和安装提供参考。
The stress calculation of directly buried heating pipeline in China is mainly in accordance with CJJ/T 81-1998 " Technical specification for directly buried heating pipeline engineering in city",but its calculation is relative complicated.In this paper,the principle and method of stress analysis by applying CAESARⅡ software are introduced,the matters for attention during calculation are discussed,and the calculation procedure and parameters selection are demonstrated through a practical example.Applying CAESARⅡ software to conduct stress analysis has the advantages of visual calculation interface and simple calculation process,thus greatly raising work efficiency.2013,3(3): 31-34 收稿日期：2012-4-16DOI：10.3969/j.issn.1001-2206.2013.03.008作者简介：王春波(1982-)，男，山东青岛人，工程师，国家注册土木工程师(岩土)，200年毕业于天津城市建设学院，硕士，现从事海洋工程结构物设计计算工作。参考文献：
