摘要
在对某河堤路基的强度进行评价时,采用了承载板法测土基回弹模量和贝克曼梁法测弯沉值两种方法进行了检测;通过实测数据,分析了回弹模量与对应的实测弯沉值之间的相对关系,以两个指标来对该段路基强度进行综合评价,并对实测关系式与经验公式进行了对比,给出了一些建议,可为今后的路基强度监测工作提供参考。
The modulus of resilience and deflection value were respectively detected with bearing plate method and Benkleman beam method so as to evaluate the strength of the subgrade of river levee. The relationship be-tween the modulus of resilience and deflection value was analyzed with the detected figures, and both of them were applied for comprehensive evaluation of subgrade strength. The expression attained by measured data was compared to empirical equation, and some advices were given for reference.
