| 摘 要： | 多数现行的管道设计方法都是以应力为基础的,但它不能完全有效解决管道设计的所有问题,特别是地面变形等位移载荷控制下的情形.从国内外管道设计标准和最新的研究进展出发,对处于极限状态的拉伸应变极限的标准进行了对比,并分析了管道拉应变极限的多种控制因素.同时,使用裂纹驱动力的理论,初步分析了拉应变极限估算方法,提出了基于应变的... |

| Abstract: | Traditional pipeline design analysis methods provided in various codes are usually based on limit stress criteria.However,these methods may be inapposite to modern steel,especially to displacement-controlled loads,such as ground displacement load.The tensile strain limit based on limit strain criteria is compared in this paper based upon various codes and recommendations,and some control factors of tensile strain limit are also reviewed respectively.In addition,presented in this paper are a basis path to th... |
