本文简要介绍了贯入试验及利用贯入试验测求土的工程地质性质指标的基本原理;通过对长春市一般建筑物主要持力层的黄土状土的微型贯入仪试验与室内土工常规试验的对比分析,经数理统计,建立了贯入阻力与土的有关工程地质性质指标的相关方程。这些相关关系,可用来快速划分土的稠度状态、土的压缩性及确定地基的承载力,对在本地区推广和使用微型贯入仪试验具有一定促进作用。
This paper briefly introduces the basic principles of the penetration test and the use of penetration testing to determine the engineering geological properties of the soil; through the micro penetration test and the routine test of the interior geotechnical engineering of the loess-like soil of the main building of Changchun City. The comparative analysis, through mathematical statistics, establishes the correlation equation of penetration resistance and soil-related engineering geological properties. These correlations can be used to quickly delineate the consistency state of soils, the compressibility of soils, and determine the bearing capacity of foundations, which will have a certain role in promoting the use of miniature penetration testers in the region.
