摘要
应用有限元方法模拟研究了一种洞库工程口部伪装用玻璃钢框架结构在荷载作用下的应力分布和变形,校核强度和刚度是否满足使用的要求.计算结果表明,移动门斜面(倾角≤60°)上布置4个储水式植物箱(单个重100 kg)和36个植草式植物箱(自重加10 cm厚土层重量)、正面分压1 640 N/m2的条件下,框架结构各杆件、植草箱和储水式植物箱的应力小于其强度值,结构稳定.研究结果表明,该型移动门能够用于沿海地区洞库工程口部伪装工程结构.
Finite element method is used to simulate the stress distribution and stress deformation of cavern camouflage fiber reinforced plastic frame structure under load in an effort to test if the strength and stiffness can fulfill the actuM needs. The calculated results show that the stress of the frame＇ s bars, planting vegetation boxes and water-storing planting tanks is lower than the intensity and the structure remains stable when 4 water-storing planting tanks （ each 100 kg） and 36 planting vegetation boxes （deadweight plus the weight of fertile soil 10 cm in thickness） are placed on the moving door inclined plane （ its dip less than 60 degrees）, and the wind pressure is 1 640 N/m2. The results indicate that this kind of moving doors can be used in cavern camouflage engineering structure in coastal areas.
