摘要
通过阐述和总结在实际项目中进行埋地玻璃钢管道应力分析时遇到的问题,给出了埋地玻璃钢管道在做管道应力分析时的注意事项和应力分析失效时的解决办法.埋地玻璃钢管道的应力分析首先必须保证其机械性能参数获得的可靠性和输入的正确性,同时还需使用者透彻理解标准规范中各项参数及各种包络曲线的含义.在分析计算结果时,可根据应力失效情况和项目要求等综合考虑以下解决方法的适用性和优先性:整体提高管道的机械性能,优化管道的设计参数,局部增强管道壁厚,修改管道路由,局部改善埋地环境等.
Abstract
This paper describes and summarizes the stress analysis issues of buried GRP pipe in actual project,and addresses the key points for special attention together with the solutions to the stress analysis failure of buried GRP pipe.In the stress analysis of buried GRP pipe,it's essential to ensure the reliability of mechanical parameters inputs.Meanwhile,it is necessary for users to thoroughly understand the meanings of various parameters and the envelope curves.When studying the calculation results,several solutions can be considered as per the stress failure mechanisms and project requirements in the according precedence order,such as overall improvement of the mechanical properties of the pipe,optimizing of the design parameters of the pipe,local enhancement of the pipe wall thickness,modification of the pipe routing,local improvement of the buried environment,etc.
