公路路基工作区深度的研究

Study on the depth of highway subgrade working section

通过对路基工作区的讨论,计算了纯土基和考虑路面结构的路基工作区深度,对比传统公式和Bisar软件的计算结果,讨论了纯土基情况下的路基工作区深度,而对考虑路面结构的路基工作区深度,通过考虑半刚性基层的作用,采用不同的开放系数进行换算,得到了更加符合实际情况的工作区深度,从而为提高道路整体的强度和稳定性奠定了良好的基础。

Through discussing subgrade working area, the paper calculates subgrade working depth of pure soil base and pavement structure discusses subgrade working depth under pure subgrade conditions, explores subgrade working depth by taking pavement structure into consideration. Through considering the role of semi-rigid base, it adopts various opening coefficients for computation, and obtains suitable working region depth, so as to lay a good foundation for improving integral rod strength and stability.
