掏挖式基础在陇东输电线路的应用

摘要

近年来，掏挖式基础在输电线路中得到广泛应用。这种基础具有充分利用原状土抗剪切特性、土方开挖量小、植被破坏面积小及施工进度快等优点，而且能够很好保护环境和减少水土流失，是当前最环保的线路铁塔基础形式之一。本文主要是结合陇东输电线路，探讨掏挖式基础的适用情况和经济效益。%In recent years, the digging foundation is widely used in the electric transmission line. The foundation has advantages of full use of anti-shearing characteristics of undisturbed soil, small amount of earthwork excavation volume, small vegetation damage area and quick schedule of construction, it is able to protect the environment and reduce soil erosion, and it is one of the most environmentally friendly line tower basis. Combined with the electric transmission line of East Gansu, this paper discusses the application and economic efficiency of digging foundation.
