| 摘 要： | 多跨连续布置钢绞线曲线形式复杂，需要解决理论伸长值的计算方法。利用规范内的计算公式，将复杂曲线分解后逐段计算，并使用计算机电算得到理论伸长值数据。通过对比厦门中洲大桥160m长钢束理论伸长值与实际量测数据，并对计算方法及施工因素进行分析，表明采用EXCEL电子表格及其函数功能进行分段计算汇总能够解决实际问题。

| Abstract: | Multi-span continuous steel hinge line layout complex curves need to address elongation value of the theoretical calculation. Regulate the use of the formula will be complicated curve decomposition after paragraph-by-paragraph basis, then used computer, elongation value of the data can be available. By comparing Xiamen Zhongzhou Bridge 160m long steel beam theory elongation value and the actual measurement data, proved using EXCEL spreadsheet functions and sub-functions can be calculated summary solve practical problems. |
