| Abstract: | According to the modern lightning protective theory and the Chinese Standard of Lightning Protection Design for Structures-GB50057-94(2000 version),this paper analyzed the direct lightning protection design for big bridges.This design contained some specific methods-definition of grades for lightning protection,air-termination system,down-conductor system and earth-termination system,for example.And good methods should be scientific,reliable,economical and reasonable.Finally,the analyses of this paper may act on the design of lightning protective engineering. |
