三、具有刚性或坚硬下卧层路面的路段中常用路面结构面层轮隙中心处辐向应力系数(?)、粒料基层中最大活动剪应力系数(?)以及基层底面 r=δ处剪应力系数(?)的计算和分析:(1)不同 E_3/E_2值对于(?)、(?)和(?)计算值的影响:1.对于(?)和(?)来说,其随 E_3/E_2变化而变化的规律曲线是一个单调曲线。在 E_3/E_2=∞-100的范围内,(?)和(?)的数值变化非常小,变化值在小数后第四位或第三位范围内;在 E_3/E_2=50-10的范围内,二者的数值比前面变化大一些,但仍在小数后第三位范围内;在 E_3/E_2=5-1的范围内,变化比较大,变化值在小数后第二位范围内。
Thirdly, the radial stress coefficient (?) At the center of the road surface layer, the maximum active shear stress coefficient (?) At the grass-roots level and the ground floor r = δ at the section with rigid or hard subsoil pavement The calculation and analysis of the stress coefficient (?): (1) The effect of different E_3 / E_2 values on the (?), (?) And the calculated values: 1. For (?) And The law of E_3 / E_2 changes is a monotonous curve. In the range of E_3 / E_2 = ∞-100, the values of (?) And (?) Change very little, and the variation values are in the fourth or third decimal places; in the range of E_3 / E_2 = 50-10 , The values of the two are larger than the previous ones, but they are still in the third place after the decimal. In the range of E_3 / E_2 = 5-1, the changes are relatively large, and the change values are in the second place after the decimal place.
