摘要
随着双层玻璃钢储油罐在国内应用的逐渐增多,对加油站将储油罐埋置在靠近加油机车道下的情况进行了储罐安全承压余量的计算,结果表明单层玻璃钢储罐的承压极限值是罐顶最大压强值的1.9倍,承压安全余量达0.9,可以证明双层玻璃钢储罐将有更高的安全系数,其刚度是单层钢质储罐的6倍以上;而现场模拟承压试验表明,双层罐在最小埋深,未用钢筋混凝土路面铺装和框架支撑时,超载133%的6轴卡车碾压的最大弹性变形仅为4 mm,车辆通过后基本恢复,不会造成较大的永久变形。
The pressure bearing capacity of double-layer FRP(Fiber Reinforced Plastics) tank is obtained through comparison with single-layer FRP tank which pressure bearing limit can be calculated. The stiffness of double-layer and single-layer FRP tank is calculated and the relative stiffness value is obtained. By simulating field situation, the maximum load vehicle compacting test is carried out on double-layer FRP tank to obtain the actual pressure bearing value. Based on the calculation, field compacting test, and investigation, the pressure bearing situation of doublelayer FRP tank under driveway is achieved, and the technical measures should be adopted in gas station construction are proposed.
