摘　　要：本文简要地介绍了孔压静力触探试验在国内的应用现状。文中包括５项内容：①探头的性能及操作；②土分类图的检验及由此所得土层柱状图的可靠性；③固结系数的确定及其与室内试验、现场原位观测推求值的比较；④利用孔压静力触探试验指标进行沉降量的计算；⑤判定土结构性的可能性。The experiences from piezocone tests in China were introduced in this paper. There were five sections :(1) probe and its operation, (2) the classification chart proposed by author and the reliability of the soil profile, (3)determination of coefficient of consolidation c h and its comparison with those measured by laboratory and field observation, (4)the method of settlement analysis using CPTU tests parameters,and (5)the possibility for interpreting the soil structure. Three examples were used to illustrate the reliability of these results.
