摘要
静力触探是一种常用的原位测试方法,目前在岩土工程勘察中得到了广泛应用,用于评估土壤的工程性质和地层结构。其主要应用包括土层划分、确定土壤的物理力学参数、砂土液化评估、桩基承载力计算等方面。为深入探究常用的双桥静力触探试验如何通过数据实现土层划分,本文针对常用静力触探不同方法以及使用原理进行调研分析,探讨所获参数在土层划分中的作用。同时,提出了将双桥静力触探设备与搅拌桩施工设备结合改进的建议,并且应用于现场施工,通过搜集分析实验数据,探究其工程适用性,以推动静力触探技术的发展。
Cone penetration test is a commonly used in-situ testing method,which has been widely applied in geotechnical engineering survey to assess soil properties and stratigraphy.Its main applications include soil stratification,determination of physical and mechanical parameters of soil,assessment of liquefaction potential in sandy soils,and calculation of pile bearing capacity.In order to deeply study how the commonly used double-bridge cone penetration test achieves soil layers delineation through data,this study investigated different methods and their principles,and explored the role of the obtained parameters in soil classification.At the same time,the proposal of integrated double-bridge cone penetration test equipment with the mixing pile construction equipment was put forward.The drilling integrated equipment was applied in field construction.Experimental data were collected and analyzed to explore the engineering applicability,aiming to advance cone penetration test technology.
