结合工程实例针对高内压下压力钢管开孔补强提出了整体加厚的设计理念,分别运用等面积法、分析法以及有限元法对该开孔结构进行了补强设计及结果对比分析,给出了压力钢管开孔补强设计的推荐思路。
Combined with engineering examples, the design concept of overall thickened was put forward for the reinforcement of the open end of the penstock under high internal pressure. The reinforcement design and the comparative analysis of the results were carried out by using isosceles method, analytic method and finite element method respectively. The recommended ideas for the reinforcement design of the pressure pipe openings.
