研究目的:针对岩石区段的接触网支柱基础,利用锚杆将基础与基岩连成整体,形成岩石锚杆基础,降低基础造价,简化施工。研究方法:依据《建筑地基基础设计规范》,充分利用岩石地基自身水平抗力极大,几乎无压缩变形的特点,直接把上部荷载通过支柱传至基岩上,通过锚杆将支柱与岩层连成整体,构成接触网支柱锚杆基础。研究结果:提出接触网支柱岩石锚杆基础计算方法,基础构造及施工做法。
Research purposes: In view of the foundation of the catenary strut in the rock section, the foundation is connected with the bedrock as a whole by means of the rock bolt to form the base of the rock bolt so as to reduce the basic cost and simplify the construction. Research methods: According to “Code for design of foundations of building foundation”, taking full advantage of the great horizontal resistance of rock foundation itself and almost no compressive deformation, the upper load is directly transmitted to the bedrock through the pillars, and the pillars are integrated with the rock strata by bolts , Constitute the contact net anchor bolt foundation. Research results: The calculation method, basic structure and construction method of rock bolt foundation of catenary are put forward.
