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。
The model tests and field tests on the foundation of the tower of the Dalat-Fengzhen EHV transmission line were conducted. The stress, displacement and failure modes in the soil were tested. The failure mechanism, the calculation method of the pull-out capacity and the displacement control calculation method were proposed.
