摘　　要：利用瑞雷波的频散特性、传播速度与岩土物理力学性质的相关特性,检测了格林科尔(南昌)科技园一期工程强夯地基质量,发现的多处低速异常区,其地基土承载力指标未达到设计要求。经钻探取样、轻便触探及土工测试,证实了该方法技术的有效性,其检测结果为地基加固处理提供了技术依据,。The Rayleigh wave technique is a new geophysical method for locating rock and soil. With its dispersion characteristics,speed of propagation and physical-mechanic properties, it can solve many engineering geological problems. This paper describes the utilization of this method in the quality inspection of the foundation treated by dynamic consolidation in No.1 construction site of Green-Cool (Nanchang) Science and Technology Yard. Some anomaly zones of low speed were found. It is pointed out that the foundation soil bearing capacity doesn't meet the designed requirements and hence some proper measures should be taken to strengthen the capacity. The effectiveness of the method has been proved by coring, light trigger exploration and civil engineering test.
