摘要
本文从不同的角度提出了两种迭加法,解决了基层有裂缝的路面在任意位置的荷载作用下的力学计算问题。特别是迭加法二,占机内存少,精度高,省机时,并可方便地用于此类路面的设计。
The paper presents two types of superposition method from different points of view, solves successfully the mechanical calculation problem on the pavement with underlying cracks or joints, especially the second superposition method has higher precision, less time for calculation and can be used convetiently in the pavement design.
