摘要
环境保护在输电线路工程中的重要性日益突出,本文研究并总结了山区输电线路环保设计的若干理念,主要结论如下:优化铁塔长短腿的极差设计,为基础配置和选用提供更大的空间;因地制宜选择性地设计特殊的塔型(如小根开铁塔、跳线上绕塔、Z型边坡塔、三角形断面塔等),可满足山区工程实际需要;优先选用原状土基础和新型环保基础型式;长短腿与不等高基础配合塔脚架使用可最大限度减少开方,建设性提出了几种适宜的塔脚架方案;山区塔基边坡推荐优先采用生态或综合护坡方案。
It is increasingly of great importance of environmental protection in transmission line project. Some Environment favoring design decepts and its protection measures are presented in this paper, including：①optimal design of unequal tower-leg is useful for tower foundation design and configure;②special design of tower type（small-base-tower, Jumper upward-strained tower, z-shape tower and triangle section tower. etc） is carry out to meet the project requirements;③the undisturbed soil foundtion and new environment favoring type should preferably be applied;④the compound technique between unequal tower leg and piers with leg-trusses are constructively put up, to minimize the earthwork project; ⑤ecological treatment for tower-foundation-slope is recommended by the above analysis.
