摘　　要：为了研究水泥路面接缝传力杆各种偏差状况,本文采用德国生产的MITSCAN2设备在黑龙江省北安至黑河高速公路的6个典型路段,共进行了142条接缝传力杆偏差状况的现场测试和数据采集工作。依据美国和加拿大制定的传力杆偏差控制标准对检测结果进行了评估,同时与美国伊利诺伊州两条公路实际检测数据进行了对比。结果表明:我国的DBI施工工艺尚处于起步阶段,传力杆偏差控制工艺需要提高;我国水泥路面传力杆偏差类型主要包括:水平移动、水平偏转、竖向移动、竖向偏转、纵向移动5种类型;水平移动偏差导致传力杆不可接受水平为1.8%,而竖向偏转偏差导致传力杆不可接受水平高达15.8%。In order to investigate the deviation status of joint dowel bar in cement pavement,by employing Germany MITSCAN2 equipment in 6 typical sections of Beian-Heihe expressway in Heilongjiang Province,the field test and data acquisition on 142 joint dowel bars are conducted. Then,the test data are analyzed and evaluated according to the control standards of dowel bar deviation proposed by United States and Canada,and the evaluation result is compared with the actual test data of 2 highways in Illinois,US. The test result shows that the DBI construction technology in China is still in the initial stage,and the deviation control technology of dowel bars needs to be improved. The main types of deviation of the cement pavement dowel bars in China include horizontal movement,horizontal deflection,vertical movement,vertical deflection,and vertical movement. Horizontal movement could result in the unacceptable level of 1. 8%,and the vertical deflection could cause the unacceptable level as high as 15. 8%.
