| dc.title | Lightning-caused disasters and lightning protection in China : past, today and tomorrow | en_US |
| dcterms.abstract | The lightning disasters situation was estimated that there were hundreds people died and billions RMB economic loss every year. This dissertation aims to provide the latest lightning disasters situation in China and also give recommendation on lightning protection work. An overview of lightning protection history was reviewed in this dissertation. The development of lightning protection in China was also provided both in policy and technical view. A summary of past 10 years lightning disasters was displayed to show the lightning protection work on the administration. The newest materials of 2007 National Lightning Disasters Statistics Report and 2007 Lightning disasters collections were used as the data sources for the situation analysis. The data was analyzed by geographical, time, industrial, rural and urban distribution etc. The data contain 818 deaths, 710 injuries, and 12494 lightning accidents cases, which show that severe casualties and economic loss are caused by lightning damage in 2007. Lightning disasters in China frequently occur in eastern coastal area and southern area, but relatively rare in western areas. Lightning disaster in China may occur in any month of the year, with less damage from October to March. 65% of the year's lightning casualties and damages occur in summer, reaching a maximum in July. The diurnal variations show that 73% of the lightning casualties and 62% of the lightning damages occur between 13:00 and 20:00. Farmers account for 92% of lightning casualties, with urban residents of 8%, which makes farmers the major population of victims. In the report with known locations for lightning victims, farmland account for 32% of the total locations as the largest category, buildings is 23%, open fields 13%, water related fields 10%, under-free fields 8%. The accidents technical analysis indicates that the design code was not sufficient to satisfy the requirement in constructions now. The analysis of typical accidents bring out the necessary of revision of design code [10]. This dissertation recommends that special supervision should be provided to the rural area in the future. It also suggests that decrease the loss of electronic equipment in lightning accident is another crucial aspect. These two main factors should be the important considerations in lightning protection work. | en_US |
