摘要介绍了落锤式弯沉仪在国内外的应用背景,在分析落锤式弯沉仪测试原理的基础上,从非线性、含水率及密实度方面,总结了利用落锤式弯沉仪分析路基性能的方法,有助于合理评价路基特性及相关参数对道路结构的影响。 The paper introduces the application background of FWD at home and abroad,analyzes FWD testing principles,and summarizes methods of analyzing subgrade performance with FWD from aspects of nonlinearity,moisture and density,which will be good for rationally evaluating subgrade characteristics and influence of relevant parameters upon road structure.
