基于路面基层最大层底应力条件下玻璃钢夹砂管涵洞的优化分析
THE OPTIMAL ANALYSIS OF THE CULVERT PIPE CULVERT OF FRPM UNDER THE MAXIMUM LAYER BOTTOM STRESS CONDITION
摘要
Abstract
The application of the glass fiber reinforced plastics mortar pipe in highway culvert becomes more and more extensive.However,due to the lack of micro-mechanical analysis of the pipeline,the application of the pipe in highway culvert engineering lacks some corresponding standards and basis.In this paper,the numerical simulation software ABAQUS was used to establish the model of surface-pipe-soil.Then,the deformation of the pipe and the stress of the bottom layer of the pavement under different conditions were analyzed.Through optimizing the thickness of the pipe wall,the optimal diameter ratio range of the pipe is obtained under the stress of the bottom layer at the critical splitting strength in different condition.Under the safety of the pavement and pipe structure,it provides some reliable analysis basis for minimizing the cost of project.关键词
