摘　　要：中国铁路电化率不足60%,随着不可再生能源的日益紧张及既有铁路运量日益不足,既有非电化电路电气化扩能改造的需求将大量涌现。既有铁路T梁桥上接触网支柱基础设计是既有铁路电气化改造的重要一环,本文针对现阶段采用的楔型锚栓有可能存在安全隐患的问题,提出采用化学植筋锚栓的方案。At present, electrification rate of Chinese railway is less than 60%. With increasing lack of non- renewable energy sources and growing shortage of existing railway traffic capacity, there will be much needs for electrification and capacity expansion reconstruction. The pillar foundation design of the overhead contact system of electrification railway on existing T Beam Bridge is an important part of the existing railway electrification reconstruction. Due to the safety risks of wedge - shaped anchor used at present, this article put forward the solution of post-installed rebar with injection mortar.
