摘　　要：本文根据双塔斜拉桥的结构特点,将斜拉桥拟成一根弹性地基梁,据此来推导车辆荷载作用下产生的内力和变形。该方法通过验证认为是一个简捷有效的方法,可供设计人员参考。According to the structural characteristics of double pylons cable-stayed bridges, we sinplify the main girders as a beam on elastic foundation. Depending on this, intenal forces and displacements, caused by lived load, are developed. Through the example, the method is verified a short - cut way, and it may give the design engineers a simple design tool to estimate the intermal forces.
