摘　　要：基于振动信号在土壤中衰减的基本原理,用重锤冲击压实度不同、含水量不同的土壤,在距锤击点一定距离处测试土壤响应信号并对信号进行分析。在大量试验的基础上,找出了反映土压实度的特征参数,得出了一种无损、快速检测土压实度的新方法。Based on the attenuation principle of vibration signal and water content is hammered, the response signal of soil near Through lots of tests, the parameters indicating soil compaction paction measure method of soil is presented. in soil, the soil with different compaction hammer point are measured and analyzed. are found and trenchless and rapid compaction measure method of soil is presented.

关 键 词：压实度 瞬态锤击 振动衰减 振动加速度
