沙漠地区输电线路铁塔基础抗拔试验

Uplift test of foundation of electric power line tower in desert area

摘要: 对达拉特—丰镇超高压输电线路的铁塔基础做了模型试验和现场试验，测试了土中应力、位移和破坏形式，提出了破坏机理、抗拔承载力计算方法和位移控制计算方法。

Abstract: Model tests and field prototype tests have been carried out for the Dalate Fenzhen electric power tranmission line towers.Measured in these tests were soil stress,soil displacements and failure patterns.Failure mechanism and methods for calculating uplift bearing capacity and for controlling uplift displacement are suggested.
