【摘要】 利用附加质量与土石混合体共振的特性,通过对单自由度线弹性系统的能量和固有频率进行分析,间接检测土石混填路基的现场密度,并用数值模拟分析方法对理论分析进行验证。对附加质量法进行现场试验,且与水袋法的检测结果进行对比,得到一致的结果。更多还原

【Abstract】 This paper,based on the characteristic of resonant vibration between the additional quality and the soil-gravel mixture,indirecdy detects the site density of soil-gravel roadbed via the analysis for energy and inherent frequency of single-freedom line elastic system,and verifies the theoretical analysis by means of numerical simulation.The paper also carries on the site test for the Additional Mass Method and compares it with the Water Bag Method,the detection results acquired form these two methods are consistent.更多还原
