摘要
对填料为天然砂砾的路基用便携式落锤弯沉仪与贝克曼梁进行了对比试验,将便携式落锤弯沉仪所得模量与贝克曼梁弯沉进行相关分析,并得到经验公式。
This article describes that the contrast tests on the subgrade filled with natural sand-gravel was conducted with portable falling weight deflectometer(FWD) and Benkelman beam,respectively,the correlation analysis on the modulus from the above tests was conducted and the empirical formula was obtained.
