This study evaluates the influence of inclined ground on the ultimate load-carrying capacity of rigid concrete pavements laying on unreinforced and reinforced soil embankments. The solution procedure is developed based on the kinematic approach of the limit analysis. The carrying capacity is sequentially obtained by satisfying the energy principle of the upper-bound theorem alongside the associated flow rule. A multi-block collapse mechanism is assumed for the intended purpose, which is later optimized to obtain the proper upper-bound limit solution. The ultimate carrying capacity of the pavement is seen to be improved further by reinforcing the embankment and modifying the soil properties. The effect of individual parameters influencing the results is discussed in detail. The available bearing capacity theories developed for rigid foundations are invoked for validation and comparison to bolster the legitimacy of the present solution.

加固土路堤上刚性路面的上限荷载——运动学方法
本研究评估了倾斜地面对铺设在未加筋和加筋土路堤上的刚性混凝土路面的极限承载能力的影响。求解程序是基于极限分析的运动学方法开发的。通过满足上界定理的能量原理以及相关的流动规则,依次获得承载能力。假定多块崩溃机制用于预期目的,稍后对其进行优化以获得适当的上限解决方案。通过加固路堤和改变土壤特性,可以看到路面的最终承载能力得到进一步提高。详细讨论了影响结果的各个参数的影响。
