A Study on Internal Force Calculation and Parameter of the Frame Beam with Pre-stressed Anchor

摘要

A supporting system-frame beam with pre-stressed anchor is widely applied to the reinforcement of slope. The force mechanism of frame beam is the priority among priorities in the system design work, since it plays an important role in the system. Based on the actual project cases, we compare the data measured in these cases and the results of the different methods of calculating on the internal force of the frame beam, to analysis the accuracy and applicability of these methods. According to the analysis, we especially concern the effect of some parameters, as the section size of beam, the coefficient of sub-grade reaction and the elongation of cantilever on the internal force of beam and sub-grade reaction.
