异型钢单缝式伸缩缝破坏原因及对策

摘要

Under the shock and vibration of overloaded vehicles,the durability of single slit type expansion joint of deformed steel is poor.It often affects the normal passage of vehicles on the highway as the expansion joints repair.Analyze the reasons,find countermeasures,is of great significance for improving the expansion joint durability.%异型钢单缝式伸缩缝在重载车辆的冲击震动作用下,耐久性较差。高速公路上经常因维修伸缩缝影响车辆的正常通行,分析其原因,找到对策,对于提高伸缩缝耐久性意义重大。
