Abstract :
Transfer mechanism of dispersive pressure anchorage body is analyzed in this paper. The supposed model improves the current anchor grouting, and compares its mechanical feature with fixed segment under load. By increasing the diameter of grouting, and relative reduction in the length, this anchorage body not only transfers load by lateral, but mobilizes its end bearing capacity. And then an example is available, the result shows that the supposed model is more scientific and effective in mobilizing formation strength, reducing the deformation, prestress controlling, and also better quantitative analysis. So this model has certain reference value to design and application of fixed anchor unit for compression dispersion-type anchor.
