Abstract：Research purposes: For building mast foundation in rock area for overhead contact wire system, the foundation can be connected together with foundation stone through anchor rod to form anchor rod foundation of mast for overhead contact wire system. In this way the engineering cost can be reduced and the construction can be simplified.
Research methods: According to “Design Code for Architecture Foundation”, the upper load can be directly transferred to the foundation stone by taking full advantage of the features of great horizontal resisting strength of rock subgrade and its seldom deformation caused by compression. In this way, the mast and rock stratum can be integrated through anchor rod and the anchor rod foundation of mast for overhead contact wire system can be formed.
Research results: The basic calculation method for foundation of rock anchor rod for overhead contact wire system, foundation structure and its construction method are put forward.
