摘要

针对几字型、高落差电缆模型的特点

发现拉管段、带中间限位的弧形垂直沉井段牵引力计算尚没有工程经验借鉴。根据实际敷设环境进行了敷设深度与弧形段高度差区段归类

分别建立了工程力学模型

采用理论计算和现场实测校核

确定工程计算公式

实现了复杂工况下高压电缆的安全、经济、高效敷设。最后以220kV牵引东站工程为例

根据文中研究成果进行优化选型并形成施工方案

高落差电缆按连续敷设工艺顺利完成了敷设和打弯工作

各项指标良好

符合技术规范要求。

Abstract

In the light of the characteristics of the cable construction model under complicated working conditions

it is found that there is no engineering experience to calculate the traction force of the stay tube section and the archigh drop section. This paper establishes the corresponding engineering mechanics models according to the construc-tion site environment

which determines the engineering calculation formulas by theoretical deduction and the on-site industrial test verification

thus realizing the safe

economical and efficient laying of high-voltage cables undercomplex working conditions. Finally

the 220kV East Traction Station project is taken as an example to verify theproposed construction scheme. The results show that the laying and bending tasks can be successfully completed and all the indicators are in perfect conformity with the technical specifications.
