Research on control technology of automatic welding for jacket pile pipes;
导管架桩管自动焊控制技术研究
In our country,even in the world,arc welding with welding rods has been used to connect platform jacket and pile pipe together for a long time,which has low welding efficiency and heavy labour intensity and becomes one of the bottlenecks affecting project progress.
海洋平台现场安装由于质量要求高、施工环境恶劣,实现自动化焊接难度大,长期以来,我国乃至世界上对平台导管架与桩管的连接一直采用焊条电弧焊,焊接效率低,工人劳动强度大,是影响工程进度的瓶颈之一。
The stress analysis and calculation are made on pile pipe buckling during marine pile driven construction for Chengdao Western EDC central jacket platform based on the rule of "The Recommendation of Plan, Design and Construction of Fixed Offshore Platform - Operational Stress Design"(API RP2A-WSD).

The settlement behavior in open-end and close-end piles was discussed in this paper based on the force-settle-ment test with eight specimens.
通过在对8根预应力敞口管桩与闭口管桩的荷载-沉降试验,对比分析研究了敞口管桩与闭口管桩的沉降特性,并得出在桩顶荷载达到第3级荷载之前,两种桩的沉降几乎相同,随着继续加载,闭口管桩沉降与开口桩相比,沉降速度减缓,在达到管桩单桩极限承载力之前,闭口管桩沉降仅为敞口管桩的30%~50%左右。
