河中输电线路杆塔基础防撞设计探讨

Discussing the Appropriate Designing Methods of the Foundation of Transmission Line Situated in the River

由于输电线路杆塔及基础自身抗撞能力较差,对于河中输电线路杆塔基础一般需进行防撞设施设计。本文参考公路桥涵设计防撞相关规定中的设计原则,结合输电线路自身特点,探讨了河中输电线路杆塔基础防撞设计原则,介绍了当前较适合河中输电线路的船型防撞挡墙和防撞排护桩两种防撞措施,并分析了各自的适用情形和特点。

Anti-collision installations will be designed when the foundation of transmission line situated in the river,because the ability of the anti-collision of the foundation is low.This article discusses the appropriate principles of the anti-collision of the foundation of transmission line situated in the river,according to the properties of transmission line,and referring to the methods of road bridge.This article also details the anti-collision cymbiform parapets and the anti-collision pies,and analyses the properties of them.
