The mechanism analysis and dynamic simulation of iced conductor galloping;

Aimed at the design of anti vibration and anti galloping of long span transmission,the scheme that the 500 kV crossing line is anti vibrated and anti galloped over Hanjiang River is studied,through which much domestic and foreign statistic data are listed from aeolian vibration,subspan oscillation and conductor galloping.

This paper expounds the problems related to flood control to flood control planning for the outlet section of Nandu River and makes an ap-proach to the principle and dertermination of planning for flood control regulation lines, the determination of relevant parameters andcalculation conditions in analizing flood and tidal levels and the calculation of wave run-up.
