ANALYSIS ON THE STABILITY OF VERTICAL BURIED GLASS FIBER REINFORCED PLASTIC CYLINDRICAL SHELL
摘要
Abstract
In order to determine the stability of vertical buried FRP cylindrical shells,several traditional formulas for stability calculation are introduced.Then,based on engineering practice,and by using the rod model without pressure bearing to solve the problem between the buried structure and the surrounding soil,the material parameter expression between the rod element and the soil is deduced,and the basic finite element calculation model is established.Compared with the traditional formula,the traditional stability formula can not be used to calculate the vertical buried structure.The influence of parameters on structural stability shows that the thickness of the structure,the elastic modulus and the elastic modulus of the surrounding soil can improve the stability and the influence of the thickness is more obvious.The structural stability decreases with the increase of shell length.In engineering application,by using the reinforcement structure to reduce the calculation length and choose the appropriate back-fill material and back-fill method to improve the elastic modulus of soil,the stability and security can effectively be improved,and has less impact on economy.关键词
