基于CBR法的矿山道路路面设计

CBR法是比较成熟的重载道路快速设计方法，需要的原始参数少，设计过程简单，目前仍被多国采用。由于现行厂矿道路设计规范无法对重载交通进行有效设计，所采用的设计方法也难以被广大矿山技术人员所掌握，因此，提出了将CBR法用于矿山道路设计的建议，按设计轮载和路基土CBR值确定所需的路面厚度，给出了路面厚度计算公式、交通荷载的计算公式和路面设计的程序，并给出了路面设计的常用参数供参考。

Design of Mine Road Pavements Based on CBR Method

CBR is a mature，fast design method for heavy traffic roads. As it needs few basic parameters and involves a simple design process，the method is still used in many countries. The current Chinese design rule for factory and mine roads can not result in an effective design for heavy traffic and the specified design method is difficult to be mastered by mine technicians. Therefore，it is suggested to apply CBR method in the mine road design. The pavement thickness is determined by the designed wheel load and the CBR value of subgrade. The calculation formulae for pavement thickness and traffic load，the procedure of pavement design and also the commonly used parameters for pavement design are given.
