| 摘 要： | 为掌握红砂岩路基现场动态模量的特点，通过便携式落锤式弯沉仪（PFWD）试验、现场承载板试验、贝克曼梁试验和压实度试验，分析红砂岩动态模量与静态模量、弯沉、压实度和含水率（稠度）之间的关系，并建立动态模量与这些指标之间的回归方程。研究表明:动态模量与静态模量、动态模量与弯沉、动态模量与压实度、动态模量与压实度和稠度均有良好的幂函数回归关系。因此，可采用PFWD来代替承压板试验、弯沉和压实度试验。

| Abstract: | To understand the characteristics of the dynamic modulus of red sandstone subgrade，the paper，through the portable falling weight deflectometer（PFWD）test，on-site bearing plate test，benkelman beam test，and compactness test，analyzed the relation between the dynamic modulus and the static modulus，deflection，compactness，and water content（consistency），as well as established the regression equation between the dynamic modulus and these indices.The study results show that there are good power function regression relations between dynamic modulus and static modulus，dynamic modulus and deflection，dynamic modulus and compactness，dynamic modulus and water content and consistency.Therefore，PFWD may be used to replace the bearing plate test，deflection and compactness tests. |
