摘　　要：随着国民经济的发展,输电线路电压等级越来越高,铁塔荷载日益增大,路径也越来越受限制。部分塔位受路径限制,需在河道中立塔,但河道中基础受力复杂,水文、地质条件恶劣。为此在已有研究的基础上,对河道内基础的受力特性、基础设计影响因素、基础造型、基础优化、基础安全措施、基础施工、基桩检测、运行维护等进行了深入、系统的研究分析,以供设计参考。With the development of the national economy,the voltage level of transmission line is getting higher and higher,the load of the tower is increasing,and the path is more and more restricted.Some tower positions are limited by the path,so they need to be set up in the river,where the foundation is subjected to complex stress,hydrological and geological conditions are harsh.Based on previous studies,the mechanical characteristics of the foundation in the river,the influencing factors of foundation design,foundation modeling,foundation optimization,foundation safety measures,foundation construction,foundation pile detection,operation and maintenance are deeply and systematically studied and analyzed for design reference.
