化工储罐雷击截收面积算法的探讨

Discussion on the Calculation Methods of Chemical Storage Tank Equivalent Area

文章在雷电灾害风险评估中使用一个恒定的位置因子来计算储罐的截收面积会导致误差的发生,本文根据储罐群以及周边建筑物的分布情况,分析了周边建筑物的高度、相对位置以及其他储罐的环绕程度对储罐截收面积的影响。结果表明:储罐之间距离的远近会使截收面积发生一定的变化,储罐之间间距与截收面积呈正相关;周边建筑物的高度及距离也会造成截收面积计算上的差异;储罐也因环绕程度不同,其截收面积存在不同。

Using a constant location factor to calculate the intercept area of the storage tank can lead to errors. Therefore,According to the distribution of the storage tank and the surrounding buildings, the influence on the height of the surrounding buildings, relative position and other tank surround degree and the tank intercept area. is analyzed.Results show that： the distance which is between the storage tank will be impact on the calculation of equivalent area, storage tanks with spacing is proportional to equivalent area; the height and distance of the surrounding buildings will caused by the difference in equivalent area calculation on; storage tank is also due to surrounding degree different, the equivalent area there are different.
