应用瑞雷波波速检测、弯沉检测、承载板试验无损检测技术对超大粒径土石混填路基强夯试验段施工质量进行检测,建立了表层剪切波波速与承载力值、表层剪切波波速与弯沉值的回归关系;以加固每m2路基所均摊的夯击能作为评价强夯施工成本的指标,推荐出土石混填路基的强夯施工优化方案;确定了山区超大粒径土石混填路基施工的工程经验法施工的参数和指标,为超大粒径土石路基施工质量控制提出了简单、易行的方法。
The application of Rayleigh wave velocity test, deflection test and load-bearing plate test non-destructive testing technique were used to test the construction quality of the large-area soil-rock mixed embankment during dynamic compaction test. The wave velocity and bearing capacity of surface shear wave, surface shear wave The wave velocity and the deflection of the value of the regression relationship; to reinforce the average spread of each m2 subgrade rammed energy can be used as an index to evaluate the cost of dynamic compaction, the recommended soil mixed concrete filled road rammer optimization construction optimization program; The parameters and indexes of engineering construction method for construction of roadbed are a simple and easy method for the construction quality control of the large diameter earthwork.
