| 摘 要： | 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。

| Abstract: | This paper shows the survey of the test, and demonstrates the essential priaciple of using micropenetrator to measure physical,mechanical properties indexis of soils. The authors did lots of comparision between penetration tests and standard laboratory tests. In these tests, the loessial said under buildings of Changchun was determined. After statistical analysis, three correlations between soil indexis bave been established, that is penetration resistance to liquidity index to allowable bearing capacity and to cofficient of compressibility. All of these are available to divide consistency states and determine bearing capacity of soils in minutes. These tests will promote the spreading and application of micropentrator in the area. |
