| Abstract: | Based on the characteristics of a collapsed gird,this paper analyzes its causes in design,construction and material.The influence of the difference between the calculating model and the real grid structure on its safety is discussed,and material tests of forty five specimens cut from the collapsed gird are carried out.The analysis and tests show that the improper design and construction are the main cause of the accident,and some suggestions about gird design and construction are presented. |
