摘　　要：准确与快速检测填土压实质量是工程施工与监理部门追求的目标,开发新的检测技术和标准,实现高质、快速和无损检测已成为亟待解决的重要任务之一。就现存及正在开发的、新的填土压实检测技术和标准,笔者从基本原理到施测技术等方面进行了全面的介绍、分析和评价,在对第一代压实系数K和第二代基床系数K30检测技术进行深入分析的基础上,阐述和介绍了第三代动刚度系数Kd和瑞利波速VR压实检测技术的基本理论、技术路线和仪器特性,并指出动态、无损。Accurate and quick checking on the quality of filled soil is the objective sought after by the departments of engineering construction and supervision.It is one of the important tasks which should be settled urgently to exploit some new checking technology and standards and bring about superior quality,quick and non-destructive checking.This paper totally introduced,analysed and appraised filled soil compaction checking technology and standard newly accomplished,and being researched and produced.Based on making penetrating analysis of first generation of compaction coefficient K and second generation of base bed coefficient K 30 ,this paper expounded and introduced the basic theory,technology line and instrument properties of third generation dynamic rigidity coefficient K d and Rayleigh wave velocity V R and pointed out that dynamic properties,nondestruction,exactitude,and rapidity will be certainly technology line of exploiting checking instrument on the quality of filled soil compaction.
