摘要
随着输电线路工程建设项目越来越多,塔基水土保持在输电线路工程中的重要性日益突出,针对山区输电线路塔基特点,对山区线路塔基的水保措施进行浅述、总结,主要结论有:工程设计阶段,贯彻水保设计基本原则,合理确定设计方案;优化铁塔设计(全方位长短腿极差设计),因地制宜设计符合工程特点的特殊塔型(如小根开铁塔、跳线上绕塔等);优化基础设计方案,优先选用原状土基础和新型环保基础型式;山区塔基边坡推荐采用生态植被护坡方案;根据塔位原始植被状态因地制宜地采取撒播草籽或灌草结合的方式对植被进行恢复;根据塔基地形、地质条件,合理选择弃土处理方案。
With the increasing number of construction projects of transmission line projects, the impact of foundation and constructionactivities on the environment has been increasing. According to the characteristics of the foundation of the mountain transmission line,this paper summarizes the water protection measures of the foundation of the mountain line. The main conclusions are as follows: in thestage of engineering design, the basic principles of water and soil conservation design should be carried out, and the design schemeshould be determined reasonably;the design of iron tower should be optimized(all-round design of long and short legs with extremedifference), and the special tower type should be designed according to the local conditions(such as small-rooted open iron tower,jump-line winding tower,etc.);the design scheme of foundation should be optimized,and the original soil foundation and new type ofenvironmental protection foundation tower should be selected first;the ecological vegetation slope protection scheme is recommended forthe foundation slope;the vegetation is restored by sowing grass seeds or combining shrub and grass according to the original vegetationcondition of the tower site;and the disposal scheme of abandoned soil is reasonably selected according to the shape and geologicalconditions of the tower site.
