| 摘 要： | 以桥梁拱脚为例，依据实验结果提出了一种模拟预应力钢索与索道壁之间接触压力等代荷载的实用的方法。通过对有限元计算结果与实验结果进行比较，可以看到此种模拟等代荷载的方法有很高的精度。

| Abstract: | Taking an arch foot as an example,a practical m et hod was proposed to simulate the contact pressure of the prestressed tendon acco rding to the experiment.Through comparing the finite element results with the ex perimental ones,the result shows that the simulating method of contact pressure has a very high precision. |
