Application of Rock Bolt Foundation in the Design of Metallurgical Industry Factory Building

摘要

Metallurgical industry factory building is usually high. Under the action of wind load and horizontal crane force, large moment will be induced at the column base. That is to say, the moment acting on the foundation is large. The embedded depth is relatively deep and the size of factory building foundation is relatively big. In the case of foundations based on the natural rock, if the routine design code adopted, the high capacity of the rock can not be fully utilized. The use of bolt at the bottom surface of the foundation integrates the foundation and the natural rock, hence reduces the foundation size and embedded depth to save the investment.
