复合地基质量检测方法及质量评定标准研究

针对复合地基质量检测的特殊性,开展复合地基质量检测技术研究,提出适宜的复合地基质量评定方法与标准。结果表明：复合地基检测需考虑成桩时间的影响,可采用静载试验、钻探取芯、动力触探、标准贯入、十字板剪切、反射波、瑞利波法等检测复合地基的强度、承载力以及成桩质量等;复合地基质量评定可采取综合评分方法,通过对不同检测内容按等级评分确定。

Quality detection methods and quality assessment standard study for composite foundation

Aimed at the particularity of quality detection for composite foundation,the appropriate quality detection methods and quality assessment standards are proposed in this paper.The results showed： it is need to consider the affect of the pile accomplished time for detecting composite foundation,and the strength,bearing capacity and pile quality of composite foundation can be determined by the methods of plate loading test,drilling,dynamic penetration test,standard penetration test,vane shear test,reflected wave and rayleigh wave etc;in additon,the comprehensive scoring method is feasible to assess the quality of composite foundation,and the score value can be detemined by different test content rating score.
