The Table 4 shows that under the action of gravity,the counterforce of the A bearing and the B
bearing are without big differences.The counterforce of the A bearing is bigger than that of the B
bearing.That is because the structure of the bridge is inclined plane and the side of A is higher than
the side of B.Under the action of 30t+30t+30t and gravity,the counterforce of the A bearing and the
B bearing are both changed.When the loads increase to 50t+50t+50t and gravity (refer with Fig.12),
the counter-force of the A bearing is -18.4KN.It shows that the A bearing is disengaging.
The load of 20t+55t+55t and gravity are located in the middle of the bridge span (refer with Fig.
13).The counterforce of the A bearing is -25.7KN.It shows that the A bearing is also disengaging.
When the load of 55t+55t and gravity are applied to the bridge,the counterforce of the A bearing is
94.1KN.The bearing A is not disengaging,but its counterforce is small.If accidental load and 55t+55t heavy vehicle run on the bridge at the same time ,the bridge is dangerous.
Conclusions The results of calculation and analysis above indicate that the stability of the bridge is not only related to the load size,but also to the load location .In order to insure the traffic security,the overload should be limited and two 55t heavy vehicles should also be forbidden.

表4说明,在重力的作用下,A支承和B支承的反作用力没有很大的区别.A支承的反作用力大于B支承,是因为桥梁结构的倾斜面,且A侧高于B侧.在30吨+30吨+30吨的重力下,A支承和B支承的反作用力都在发生变化.当负载增加到50吨+50吨t+50吨和重力（参见图13）, A支承的反作用力为18.4KN, . 当20吨+55吨+55吨载荷和重力位于桥跨的中间时（参见图13）,A支承的反作用力为-25.7KN.它表示A支承也在脱出.当55吨+55吨和55吨负载和重力施加于桥梁时,A支承的反作用力为94.1KN.A支承没有分离,它的反作用力很小.如果偶然载荷和55吨+55吨的重车同时在桥上通过,桥梁就会很危险.

总结以上计算和分析的结果表明桥梁的稳定性不仅仅是负载的大小,更重要的是其受重的位置.为了保证交通的安全,必须限制超载和必须限制两辆55吨车同时通过.
