摘　　要：梁格法是一种空间计算分析的方法,具有清晰、易理解等特点,广泛引用到宽桥、异形桥等的计算分析。在桥梁静载试验理论分析中,它能得到主要控制截面的挠度、应变数据,以满足宽箱梁桥静载试验的理论计算要求。基于梁格法理论,采用空间梁格法对某连续宽箱梁桥进行分析,计算分析了设计活载静载响应,得出主要控制截面的横向测点理论计算值,并根据现场静载试验结果对该桥进行评估。对梁格法在桥梁静载试验应用中提供了借鉴和参考。The grillage method is a kind of space calculation and analysis method, possesses the characteristics of clear and easy to understand and is widely used for the calculation and analysis of wide bridge and special-shaped bridge. In the theoretical analysis of bridge static load test, this method can get the deflection and strain data mainly to control the section in order to meet the theoretical calculation requirement of static load test of wide-box girder bridge. Based on the theory of grillage method, the space grillage method is used to analyze a continuous wide-box girder bridge, calculate and analyze the static load respond of the design live load, and give the theoretical calculation value of transverse test point mainly to control the section. Based on the static load test result of site, this bridge is evaluated, which can provide the reference for the application of grillage method in the static load test of bridge.
