山区输电线路的环保设计和措施研究简

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。

Design and Measures of Environmental Protection of Transmission Line in Mountain Area

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.
