路面结构计算的有限元混合法

（目的）采用一种新的方法进行路面结构计算。（方法）利用有限元混合法可以解决路面结构中的弯沉值和弯拉应力等的计算问题。（结果）有限元混合法考虑了弹性体各结构层间的材料异性和接触状态，而在其接触面引入了成对的接触点对，以表现其接触的过程。在形成接触体系的刚度矩阵后，可以求解出弹性体接触内力，进而完成全部问题的求解。（结论）该方法对各结构层单元的位移求解完成后，通过物理方程便可以计算出单元的应力，对路面结构计算具有一定的参考价值和指导意义。

Mixed Finite Element Method in Calculation of Road Pavement Structure

(Aim)Adopt a new method for calculating in road pavement structure. (Method) Make use of mixed finite element method can to solve the calculation problems of deflection value and flexural-tensile stress in road pavement structure.(Result)Mixed finite element method considers the anisotropic materials and contact states in elastomeric structure layers,and each pair of contact points is introduced in a contact surface,just to express contractile process. The elastic contact force can be solved after stiffness...
