高速铁路路基A、B料压实质量检测方法、标准的探讨

研究目的:通过采用地基系数K_(30)、动态变形模量E_(vd)、孔隙率n 3种不同检验方法对京沪昆山试验段试验段采用A、B料湖州碎石土填筑路堤压实质量进行检验、分析研究,从而提出高速铁路路基A、B料检测合理标准、方法。研究结果:通过对大量昆山试验段A、B料碎石土路堤质量检测数据分析,得出了对高速铁路路堤质量检验标准及方法的建议。

Discussion on the Test Method and Standard for Compaction Quality of Materials A and B for High-speed Railway Subgrade

Research purposes:With three different test methods of foundation factors K_(30),dynamic deformation modulus E_(vd) and porosity n,the tests and researches are done on the compaction quality of materials A and B's crushed stones to fill the embankment in Kunshan Experimental Section of Beijing-Shanghai High-speed Railway for the purpose of providing the method and standard for testing the compaction quality of materials A and B for high-speed railway. Research results:The proposals to the test method and standard for embankment quality of high-speed railway are presented through doing lots of tests and making analyses of the quality of the embankment filled with materials A and B in Kunshan Experimental Section.
