摘要
ＷＧ－１型微型贯入仪是为建筑、工程地质专业创造出的一种新型测试仪器。操作简便，提交成果快。但生产厂家提供的查对表参数值的准确度局限于当地。不能广泛用于地基土特性多变的其他地区。为适应不同地区的需要，我们作了大量试验，探求出一套建立经验公式和查对表的统计计算方法。依据均质土特性相同的理论基础，将微型贯入试验与土工试验和标准贯入试验同步比照进行，从已知求未知，采用《修正曲线方程》￣［１］法，建立了有关土指标的经验公式和参数查对表。经生产实践验证，误差很小，可供推广应用。
WG-1 micro-penetrometer is a new type penetrometer used to building,engineering geol-ogy,and easy to operate,quick to obtain the result.But,the firm offered the parameter tableonly limited to the locality,but can’t extensively use in the other area.We seek out a set of cal-culating method and set up an experiential formula in order to fit for the needs varied areas.Based on the basic theory of homogeneous soil having the same characteristics,comparing thethree results of micro-penetration,the geotechnical test and the standard penetration using themethod of corrected curvilineal equation,we set up a empire formula and parameteric check list.Through a great deal of practical examination,it shows that the error is very small and can beused.
