摘要
在现有压实检测技术的基础上,通过分析振动轮 土壤系统的力学模型,建立了相应的运动方程.通过仿真,得到了振动加速度与土壤刚度和阻尼的关系,据此提出通过检测振动轮振动加速度间接反映土壤压实状况的压实度自动检测原理.开发、研制了自动检测系统并应用于工程实践,实测结果验证了振动加速度与土壤压实度之间的强相关性.
On the basis of the present methods of compaction testing, the mechanical model of a vibrating roller-soil system was analyzed and its dynamic equation was established. The relationship between vibration acceleration and soil rigidity and soil damp was obtained by simulation. Based on the simulation result, the auto-testing principle of compaction degree was put forward, i.e. through testing the vibration acceleration of the vibrating roller, the soil compaction status can be reflected indirectly. A auto-testing system was developed and applied to a project, and the strong relativity between soil compaction degree and vibration acceleration was verified.
