摘　　要：特殊性土指自然界中具有特殊的物理、力学、化学性质,并影响工程地质条件的土。由于岩土特征的特殊性,在由这类岩土构成的建设场地进行岩土工程勘察时,往往需要使用一些专用的勘察工具来进行勘探和取样工作,从而获取符合实际情况的岩土力学及物性等指标数据,搞好特殊性土地区的岩土工程勘察工作。The specificity of soil refers to the special nature of the physical,mechanical and chemical properties,and has influence on engineering geological conditions of the soil.Owing to the characteristics of the soil some special tools are need to be used for exploration and survey sampling during geotechnical engineering investigation on those sites with the specificity of soil, So the index data of geotechnical mechanics and geotechnical properties can be obtained to improve geotechnical engineering investigation work on the particular soil ground.
