本文给出了多层路面上、中层(半刚性基层)拉应力简化计算的一个新方法。这个方法考虑了路面结构传布荷载的特性,把荷载扩散后的d引用到简化计算公式中,使计算的精度有一定的提高。为了说明问题,文中对数十组不同模量比和厚度比例的四、五层体系之上、中层拉应力,进行了精确解、路面新规范法和简化新法计算,并给出了它们的计算精度比较。
In this paper, a new method of simplified calculation of tensile stress on the middle and middle layers of semi-rigid pavement is given. This method takes into account the characteristics of the spread of pavement structure load, the d after the load spread to simplify the calculation formula, the calculation accuracy is improved. In order to illustrate the problem, the exact upper solution and the new normalized pavement method and the simplified new method are applied to the upper and middle layer tensile stress of dozens and sets of four- and five-layer systems with different modulus ratios and thicknesses, and their calculations Accuracy comparison.
