WU Xuan-tao1,ZHOU Zhi-xiang1,ZENG Fan-jiang2(1.Chongqing Jiaotong University,Chongqing 400074,China; 2.Department of Transportation of Youyang District,Chongqing 409800,China)  
The reasons for the cracks in the reinforced concrete block of curved girders were analyzed,and the formula for calculating the stress of reinforced concrete block under the effect of centrifugal force of cars was provided through the finite element software ANSYS.The measures to avoid the reinforced concrete block from cracking were discussed,which could provide the baseline for the design and construction of the reinforced concrete block.
