摘要
静力触探方法是工程中广泛使用的一种原位测试方法。通过归纳分析国内外相关资料,概述了静力触探仪器设备发展历程。系统归纳静力触探锥头贯入阻力理论研究,以及模型试验、数值模拟、成果应用等研究。应用静力触探主要有以下几个方面:(1)确定土的名称及划分地层;(2)地基承载力;(3)估算单桩容许承载力;(4)检验地基强度及评价地基土震动液化等。
Static cone penetration test is an in-situ test method widely used in engineering.By summarizing and analyzing the relevant data at home and abroad,this paper summarizes the development process of CPT instruments and equipment.Systematically summarize the theoretical research,model test,numerical simulation and application of cone penetration resistance of static cone penetration test.The application of CPT mainly includes the following aspects:(1)Determining the name of soil and dividing strata;(2)Foundation bearing capacity;(3)Estimate the allowable bearing capacity of single pile;(4)Inspect the foundation strength and evaluate the vibration liquefaction of foundation soil.
