摘要
针对架空输电线路铁塔基础在地下裂隙潜流地段设计中所选用的形式,对比分析了重力式基础、掏挖基础、人工挖孔桩三类基础的选型原则及受力特点,最后结合工程实例,对三种基础的工程材料量以及综合造价进行了比较,指出采用人工挖孔桩比较合理。
In view of the type selection of overhead transmission line iron tower foundation in underground crack subsurface flow section design, through the comparison of mechanical characteristics of gravity foundation,dig dug foundation and artificial dig hole pile three foundation,ana-lyzed the selection principle and mechanical characteristics,finally combining with the engineering examples,compared and analyzed the engi-neering material amount and comprehensive cost of three kind of foundation,pointed out that using artificial dig hole pile more reasonable.
