Abstract Steel tube tower in heavy load transmission line shows its effectiveness and good performance, but also has the the disadvantage of Limited variety and high specifications price, at the same time, steel pipe connection joints construction is complex, production efficiency is low, so it is necessary to study the application of steel tube tower under typical load conditions. To carry out comparative study of angle steel tower, steel tower, this text analysis the main trend of steel tube tower cost changes as well as the key factors of the cost change,considering the 10mm、15mm icing condition, along with the change of wind speed. Finally, this paper assumes that the angle steel tower material price under the premise, through the adjustment of the price of steel tower, changing the price ratio of angle steel tower tower material to compare and analyses the economy. of steel tower and angle steel tower.

Key words： steel tube tower sensitivity analysis single factor analysis engineering cost
