摘要: 用于路基弯沉检测的单后轴车(标准车)产量日趋减少,为使路基弯沉检测更为完善、合理,采用较为常见的双后轴车进行路基弯沉检测,探讨了测量方法,对比分析了单、双后轴车在相同路基上其弯沉之间的关系;依据弹性半空间体理论,分析了两者间的关系。结果表明:双后轴车可用于路基弯沉检测,且单、双后轴车所检测的弯沉值之间存在较好线性关系。

Abstract: The output of single rear vehicle (standard vehicle) has been decreased gradually. In order to make the roadbed deflection testing more perfect and reasonable, the common double rear vehicle was used to do test deflection, and the method of measuring was also discussed. And then the relationship of single or double rear vehicle deflections under the same roadbed were analyzed and contrasted. At last the roadbed deflection relationships between single and double rear vehicle were analyzed based on the theory of elastic semiinfinite body. The results show that: the double rear vehicle can be used in roadbed deflections detection, and the deflections between single and double rear vehicle are linear.

Key words: road engineering, roadbed test, deflection, testing method, double rear vehicle
