摘　　要：根据梯形分块法、累加法及区间二分法理论,编制了混凝土截面特性计算程序,可快速方便地求解混凝土桥梁截面的毛截面特性、全截面及开裂截面换算特性,解决了繁琐的手算计算工作,经实例验证,其结果可靠,可推广应用。In this paper,the calculation program of the concrete cross section is compiled according to the trapezoidal block method,the accumulation method and the interval dichotomy theory.It can quickly and easily solve the gross-cross-section properties,the total-cross-section properties and the crack-cross-section properties of the concrete bridge.The program which was successfully designed can avoid complex calculating,improve precision and save time.Some examples showed that the accuracy of this program was well.
