At the same time,it designed the project of construction supervision and measure aimed at the strengthening bridge by external presttessing,through the contrast between the result in theory and fact,we can see that it is feasible to use predigestion's computing based on elasticity to analyse continuous rigid frame briges reinforced by external presttessing ,and it can ignore the effect of the second stress. So, it can be capable of the analyses in the strengthening bridge by external presttessing using the method of controlling by flexibility and stress to set up the model of scathe,and,the method of external presttessing can ensure stress reserve of the main beam, to reduce effectively PrinciPal tensile stress, to renew line state of bridge structure and gradient.

Under small-scale yield condition, the stress distribution outside the yield zone is similar to singular stress distribution without considering the plastic yield. So the elastic singular stress field can be used to narrate the elasto-plastic stree field approximately under small scale yield condition, but the stress intensity coefficient is larger that the elastic one, moreover, it increases as the hardening coefficient decreases.

There is much difference between the stress ratio in crown and springe calculated with these two methods. In the crown, most external forces changing into horizontal forces leads to the large decrease of the vertical tension stress. The vertical distribution pattern of the axial forces in the arch and soil pressure is not the same. And near the bottom of the pit the axial tension stress appears. Due to the self-accommodation effect which the external force acts on the arch, the stress in the springe gets lesser too.

拱冠和拱脚处的应力比值跟竖向构件比较相差悬殊；拱冠处由于大部分外力转化为水平拱内轴压力而使得竖向拉应力大大减小；竖向上拱内轴力与土压力的分布模式并不相同，并且在坑底附近出现了轴拉力；拱脚处也由于拱体对外力的自我调节作用而变得比纯竖向构件小的多。
