一、前言我国正在迅速开发近海油田,近海工程结构物的设计、建造和检验等方面的科研工作已在开展,固定式海洋平台是研究内容之一,目前多数固定式钢制平台是由钢管焊接而成,因此焊接管节点的强度和疲劳分析是海洋平台安全设计的关键,世界各国都很重视这个问题的研究,并进行了大量管节点的试验。大尺寸管节点的试验是很复杂的,需要大量人力、时间、经费和专用设备,为了科研中少走弯路,借荐国外已取得的经验,本文收集了近几年国外管节点的试验情况及主要结果,简介于后,供有关同志参考。
I. Introduction China is rapidly developing offshore oilfields. Scientific research on the design, construction and inspection of offshore structures has been carried out. The fixed offshore platform is one of the research contents. At present, most of the fixed steel platforms are welded by steel pipes Therefore, the strength and fatigue analysis of welded pipe joints are the key to the safety design of offshore platforms. All countries in the world attach great importance to this issue and test a large number of pipe joints. The test of large-sized pipe joints is very complex, requiring a lot of manpower, time, funds and special equipment. In order to avoid detours in research and to borrow the experience gained from abroad, this paper collects the experimental conditions of foreign pipe joints in recent years The main result, after brief introduction, is for reference by the relevant comrades.
