摘　　要：为了验证扁铲侧胀试验中获得的材料指数试验结果与岩土类别的数据关系,在武汉及汉江流域布置1000个试验探头开展扁铲侧胀试验与钻孔岩心试验的关联研究。结果发现:扁铲侧胀法在武汉及汉江流域有较强的工艺适应性;扁铲侧胀试验对黏土、粉质黏土、粉土、砂土的适应性较强,在圆砾土、卵石土等含有大粒径高硬度颗粒的土层中不适用。In order to verify the relationship between the material index test results obtained in the flat dilatometer test and the data of geotechnical categories,1000 test probes were arranged in Wuhan and Hanjiang basin to carry out the correlation study between the flat dilatometer test and borehole core test.It is found that the flat dilatometer method has strong process adaptability in Wuhan and Hanjiang basin.The flat dilatometer test has strong adaptability to clay,silty clay,silt and sand,but is not applicable to the soil layers containing large-size and high hardness particles such as round gravel soil and pebble soil.
