摘要
通过大量的统计数据,利用数理统计原理构造合适的统计量,选择适当的置信度分析了某线路输电铁塔K节点变形。通过与理论计算变形值的比较,给出了由于加工原因而累积的变形值。分析了铁塔在架线前和架线后的变形值的合理范围,同时应用假设检验理论对该工程某标段进行了评价。
Based on numerous statistical data, the K nodes＇deformation of an electricity transmission tower is analyzed with a proper confidence degree and statistics by applying the mathematical statistics principle. The accumulated deformation value induced by manufacture is obtained by comparing the theoretical values of the deformation. The rational values of deformation before and after stringing construction are studied. Meanwhile, a certain part of the project is evaluated by using the hypothesis testing theory.
