十万立方米外浮顶储罐设计 摘 要：近一、二十年来，油罐的设计与施工技术较过去都有了更快的发展，明显的趋势是大型化，油罐大型化给人们带来许多经济利益，也带来了一些技术课题。浮顶油罐是目前国内外在大中型油罐中最常用的一种结构形式，它几乎全部消灭了气体空间，从而大大减少了油品的蒸发损耗和大气污染等。地区地质状况良好，适合建罐，设计基本风压为800Mpa，对钢材的选择考虑了强度，可焊性和冲击韧性三项主要要求。罐壁厚度计算采用变点设计法，分别计算了充水和储油两种不同储存介质的情况，用它计算大容量罐时，可减少某些圈的壁厚和罐壁总用钢量。设计中不仅包括了罐顶，罐壁，罐底的整体轮廓计算，还包括抗风圈，加强圈和密封的计算，抗风圈和加强圈设计采用我国国内标准。油罐的抗震设计也参照国内外的设计规范，可承受8级以上的地震。校核部分包括浮顶四个准则，强度和稳定性校核，下节点校核以及开孔补强校核。 计算部分清楚简洁，图纸清晰规范，在保证安全的前提下，经济选材是本设计的特点。 关键词：浮顶油罐，浮顶，罐壁，抗风圈，加强圈 Abstract：Recent one or two decades, the design and construction of tank technology has been faster than in the past the development of a clear trend that large-scale and large-scale oil brings many economic benefits as well as a number of technical issues .Floating roof tank is the large and medium-sized oil tank at home and abroad in the most commonly used form of a structure, it eliminated almost all of the gas space, thus greatly reducing the evaporation loss of oils and atmospheric pollution. Geological in good condition and suitable for cans, for the design of the basic wind pressure 800Mpa, on the choice of the steel strength, weldability and impact toughness of the three main requirements. Calculation of tank wall thickness design method using change-point, were calculated and the reservoir water storage of two different media, the use it when calculating the large-capacity tanks can reduce certain circle tank wall thickness and the total amount of steel. Design includes not only the tank top, tank walls, tank at the end of the overall outline of the calculation, but also wind circle, strengthening and sealing ring, the wind and the strengthening of circle circle design standards in China. Seismic Design of oil tank at home and abroad is also reference to the design specifications can withstand earthquakes of more than 8. Check some of the four criteria, including floating roof, the strength and stability of calibration, the next check node and check opening reinforcement.Calculation of some clear and concise
