The SZKT large crossing tower used in the Yangtze River crossing of Three Gorges Youjing 500 kV transmission line project is constructed using combined lifting pole method,which combines guyed lifting pole and A-frame lifting pole.

A successful sample of crossing-sea engineering in Putian is explained,which shows the history of fresh water delivery to islands by shipping being finished.

The development of IMS for steel tower manufacturing enterprise based on Delphi;

The Finite Element Analysis of Steel Towers In Aired Power-sending Line;

Through the theoretical calculation of the steel tower core,the hoist bearing capacity,the suspending point bolt stressing,the steel wire rope maximum working tension,the plate tensile stress and the bolt joint center distance,the assembly scheme by hoist is designed.

Introduction of 750kV transmission tower group erecting methods;

To solve the problem of foundation collapse existing in the design and operation of transmission lines located in coal-mining fields, the authors propose a new design idea for transmission tower with adjustable height in adaptation to uniform foundation settlement, and a design scheme for KTZM110 cathead tangent tower with adjustable height is accomplished.

According to the damage cases on transmission tower under strong wind,probability statistic expression of pulse wind velocity and pressure are investigated by the auto-regressive model(AR model)in time series analysis,the time history of pulse wind load acting on transmission tower structure and varying along with the space positions has been concisely.
