摘　　要：对既有及正在开发中的填土压实检测技术的原理及实测方法进行了系统的介绍、分析及论证。在此基础上,阐述了开发填土压实检测与压实机械集成系统的必要性、研制机载集成系统时所依据的力学模型、实现途径及国内外关于压实机械集成系统研究、开发的最新进展,介绍了压实机械集成系统的工作原理及工作特性,同时指出了为适应当前及未来土建工程对填土压实质量(特别是沉降量及沉降速率等方面)的基本要求,应以填土压实层的力学强度(K30、动刚度系数等)作为开发压实机械集成系统时的参考对比指标。This paper introduces, analyses and appraises the principle and operating rule of newly and existing earth-filled compaction checking technology. Based on making penetrating analysis, this paper expounds the necessity, mechanical model, the accomplishing ways and newly international preparing advance of developing compaction machine assembling system. The basic principle and working properties of compaction machine assembling system are also described; and that for satisfying basic needs of earth-fill compaction quality in civil engineering (such as quantity of settlement, rate of settlement and so on) the mechanical intensity (such as K30, dynamic rigidity coefficient and so on) should be taken for standard of reference in preparing compaction machine assembling system.
