摘　　要：近年来连续压实控制技术已在奥地利等西欧国家得到较为广泛的应用,各国根据各自的系统设备提出了不同的检测工作原理和评价分析方法,编制了各自的技术规程。本文详细介绍了包括欧盟标准在内的国内外连续压实控制技术标准与规范,共6部规程。重点分析了各国规程的测值计算方法和质量控制标准等方面内容,对比研究了各国规程技术特点和应用条件,总结了该技术在世界各地的应用经验。结果表明:(1)综合评估填筑体的压实程度、压实均匀性和压实稳定性具有明显的先进性,是质量控制标准发展的趋势;(2)各类检验方法的技术特点和应用条件均有所不同。针对工程实际中不同的周边环境、场地条件、填料特性和工程性质等特点,以目测值校准法为主,薄弱区域识别法结合测值增量法为辅,合理选用评价方法是促成连续压实控制技术成功应用的有效途径。In recent years,continuous compaction control technology has been widely used in Western European countries such as Austria.Countries have proposed different testing working principles and evaluation analysis methods according to their respective systems equipment,and compiled their own technical regulations.This paper introduces in detail the domestic and international continuous compaction control technology standards and specifications,including EU standards.There are 6 procedures in total.This paper focuses on the analysis of the measurement calculation methods and quality control standards of the national regulations,compares the technical characteristics and application conditions of the national regulations,and summarizes the application experience of the technology in the world.The results show that:(1)comprehensive evaluation of the compaction degree,compaction uniformity and compaction stability of the filling body has obviously advanced,which is the trend of quality control standard development.(2)the technical characteristics and application conditions of various inspection methods are different.Aiming at the characteristics of different surrounding environment,site conditions,filling characteristics and engineering properties in engineering practice,the effective way to promote the successful application of continuous compaction control technology is to take the visual value calibration method as the main method,the weak area identification method combined with the measurement value increment method as the auxiliary,and reasonably select the evaluation method.
