落球与传统密度检测法检测压实度对比研究

Comparative Study on the Compaction Degree by Falling Ball and Traditional Density Detection Method

以一种材料不同压实遍数以及不同岩土材料为研究对象,将传统密度检测技术与落球检测技术结合三个实际工程项目进行对比分析。落球检测与传统密度检测压实度、干密度和K30具有很好的相关性;变形模量与落球检测和传统密度检测干密度也具有很好的相关性。落球检测技术可以代替传统检测技术检测干密度、压实度和K30,为今后落球检测技术在全国的推广应用提供相应的理论基础和数据参考。

With a material of different compaction and other different geotechnical materials as the research object, the traditional density detection technology and drop ball detection technology have been compared based on three practical engineering projects. The results show that drop-ball detection has a good correlation with conventional density detection compaction, dry density and K30, and deformation modulus has a good correlation with drop-ball detection and traditional density detection dry density. Drop ball detection technology can replace the traditional detection technology to detect dry density, compaction and K30, and it could provide theoretical basis and data reference for the future application of ball dropping detection technology in China.
