摘要
从设计应力出发,提出了对CJJ63—2008《聚乙烯燃气管道工程技术规程》中PE管道最大拖拉力的修正公式,分析了修正公式与规程公式的异同点以及修正公式的意义,探讨了修正公式中总体设计系数的取值,指出了修正公式仍然存在的缺陷,提出了建议。
The correction formula of maximum traction force of PE pipeline in Technical Specification for PE Gas Pipeline Engineering （ CJJ 63 - 2008） is proposed based on the design stress. The similarity and difference between the correction formula and the formula in the specification and the meaning of the correction formula are analyzed. The value for the overall design coefficient in the correction formula is discussed. The deficiencies of the correction formula are put forward, and some suggestions are given.
