摘要
举例介绍了预应力施工钢束理论伸长量的3种不同计算方法,经过具体的计算并对其结果进行了对比分析,不论是理论上还是通过大量的桥梁预应力施工的实践证明:分段计算理论伸长量是最准确、最合切实际的方法。
In this paper, three kinds of length- extension calculation methods of prestressed construction are introduced. Through analyzing and comparing the calculation results, It is found that the segment calculation meth- od is the most accurate and practical method.
