《油气储运》1987年第2期发表了梁政、袁祥忠两同志的“埋地长输管道水平弯头升温载荷下的计算问题”一文,该文应用弹性地基梁理论来分析水平弯头的有关问题,给在埋地弯头的设计计算中提供了又一种方法。现就文中的两个问题与作者商榷。 1.关于弯头点热胀位移的几何关系 文中原图4(见图1)给出的几何关系采用了参考文献[2]推算的几何位移关系式 “Oil and gas storage and transportation” 1987 the second issue of Liang Zheng, Yuan Xiangzhong two comrades “Buried long-distance pipeline under the conditions of the temperature rise of the elbow load,” a text, the article using elastic foundation beam theory to analyze the horizontal elbow Of the relevant issues, in the design of buried elbow provides an alternative method. Discuss the author with two questions on the text. 1. Geometrical relationship of elbow point thermal expansion displacement The geometric relation given in the original figure 4 (see Figure 1) adopts the geometric displacement relation deduced in reference [2]
