摘要
以各国规范中的徐变系数计算模式为理论基础,利用桥梁专业软件Midas/Civil对秦沈客运专线跨土河桥跨中上拱度理论值进行了计算,并结合对该桥长期观测所取得的实测数据进行对比分析,研究发现,现行规范能够更加切合实际地反映工程实际情况,具有一定的普遍性及适用性。
Taking creep coefficient calculation modes in standards of different counties as theoretical base, the camber value of bridge span in Qin-Shen passenger dedicated line Kuatu river was calculated using bridge special software Midas/Civil, which was compared with the measured data by long-term observation to this bridge, it can be concluded that current code is a more feasible method to reflect engineering practice situation, has a certain universality and applicability.
