摘要

本文主要就戈壁滩地区输电线路掏挖基础的工程应用进行研究,掏挖基础相对于不扩底的墩拥有较好的抗拔、抗压、抗倾覆特性。这里通过有限元软件对掏挖基础进行三维建模分析,考虑土质条件、桩土接触等因素,着重针对荷载传递、整体剪切的破坏机制以及影响范围等进行分析,验证掏挖基础工程的可行性,及对周围环境的影响范围。
        This paper mainly studies the engineering application of the excavated foundation of the transmission lines in Gobi area, and excavated foundation of belled piers with respect to non expanding piers have some better anti pull, compression, anti overturning characteristics. And in this paper, the finite element software is used to analyze the threedimensional modeling of excavated foundation, which the soil conditions and the contact between pile and soil are considered, and the finite element analysis is mainly carried out for the failure mechanism and the influence range of the load transfer and the whole shear, verifying the feasibility of digging foundation engineering, and the scope of the impact on the surrounding environment.
