塔形井架绷绳系统的计算

Calculation of the Guyline System for Steel Derricks,

以数学分析中悬链线理论为基础,根据力学、建筑学的有关理论和方法,导出了井架绷绳系统(包括绷绳和地锚)的全部计算公式,并以TJ_2—41型塔形井架为例,对现行绷绳系统参数和井架抗风能力进行了分析计算。阐明了井架发生倾倒的重要原因,并就绷绳系统的合理使用提出了若干建议。

On the basis of the funicular curve theory and the relevant theories in mechanics and architecture, the authors work out all the formulas for the calculation of the guyline system(including guy anchors). Taking Model TJ_2-41 derrick as an example, the authors make a. study of the parameters of the guy system and the allowable wind loads on the derrick, expound the main causes of toppling over of the derricik, and offer some recommendations for proper installation of the guy system.
