辽宁省典型公路路基动静弯沉相关性研究

摘要

选取辽宁省典型公路的路基进行贝克曼梁弯沉试验和FWD弯沉试验,基于不同贝克曼梁弯沉测试值范围内的动静弯沉代表值,开展了动静弯沉的转化关系模型研究,提出了适合于辽宁省的路基动静弯沉转化线性模型,进而提出了相应的基于FWD的路基动弯沉验收标准值.%Beckman beam deflection test and FWD deflection test are performed on Liaoning typical highway subgrades.Basing on typical values of dynamic and static deflection within the range of testing values of different Beckman beam deflection, the research on models for transforming relationship of dynamic and static deflection is made, and transforming linear models that are suitable for dynamic and static deflection of Liaoning subgrades are put forward, so as to provide corresponding acceptance standard values for subgrades basing on FWD dynamic deflection.
