According to actual performance of rigid and flexible surface layer , visco - elastic model and elastic plates model are adopted to respectively simulate flexible and rigid surface , and the foundation is considered as transversal isotropic elastic body 基于面层的实际特征,分别采用粘弹性模型和弹性薄板模型模拟刚性和柔性面层,地基则采用了本文所探讨的地基模型。
