摘　　要：针对某高速公路的一系列连续梁桥进行的静力荷载实验进行概述,选取跨数及跨径两个参数,对其试验得到的实测挠度及应变结果进行分析研究,进一步量化分析该参数对连续梁桥承载力的影响,此外基于MIDAS/Civil软件,建立了不同跨径连续梁桥的有限元模型,模型计算结果验证了多参数分析结果的可靠性,该分析方法可以应用于指导同类连续梁桥的荷载试验方案设计中。A series of continuous beam bridge static load experi-ments for a highway were summarized, and the two parameters （the number of span and the span） were selected to analyze the measured deflection and strain results of the load tests. The fu r-ther quantitative analyses of the influence of the two parameters on the continuous beam bridge ＇ s bearing capacity were conduc-ted. In addition, the f ini te element model of different span contin-uous beam bridges was established based on MIDAS/Civil soft-ware. The calculation results of the model ver if ied the reliability of multi parameter analysis results, the analysis method can be used in guiding the design of simi lar continuous beam bridge load experiment scheme.
