摘　　要：海洋平台是常见的海洋钢结构,广泛应用于海洋石油及天然气的开采,作为海洋平台的主体部分的结构框架,主要通过焊接进行连接,而焊接过程产生的残余应力将可能导致结构发生尺寸变形,尺寸变形会对海洋平台的整体性能产生不利影响。探讨了结构焊接尺寸变形的控制方法。Off-shore platform is a kind of steel structure,which is widely utilized for exploration of off-shore oil and natural gas. Structure discipline is the main composition of platform,which is mainly connected by welding,nevertheless,residual stress which results from the welding process may lead to deformation of structure,furthermore,the deformation may have a bad effect on the overall property of platform. This text details the dimensional control measures of structure welding.
