摘　　要：随着国民经济和综合国力的不断发展和提升,高速公路的建设的步伐也在持续的加速,拼宽结构已得到广泛的应用。本文以实际工程为例,根据结构特性与现场实施条件制定相应的荷载试验方案,并对加固拼宽部分以及拼宽部分与原结构的受力情况进行分析和判断,可为以后高速拼宽桥梁的检测提供参考。With the continuous development and promotion of the national economy and the comprehensive national strength, the pace of the construction of the expressway is also accelerating, and the wide structure has been widely used. This paper, taking practical engineering as an example, formulated the corresponding load test scheme according to the structure characteristics and the site implementation conditions, and analyzed and judged the strength of the widening part, the widening part and the original structure, which can provide reference for the detection of the high-speed bridge in the future.

关 键 词：拼宽桥梁 荷载试验 承载能力
