软土、残积土的液、塑性指标的试验方法探讨

Testing Method of the Fluid and Plastic Index of Soft and Residual Soil

在工程实践中 ,粘性土的可塑性指标是评价土的工程性能的重要指标 ,但在工程实践中软土、残积粘性土室内土工试验方法不同 ,得出的液、塑限指标差别颇大 ,与野外鉴定亦不一致。就软土、残积土的液、塑限指标的试验方法与工程实例进行对比分析 ,确定符合野外实际的试验方法。

The plastic index of co hesive soil is an important one in the evaluation of soil engineering property in the construction. But the fluid and plastic index of soft and residual soil, obtained in the laboratory is not identical with those obtained in the field and is quite different due to different laboratory geo technical testing method. The comparison and analysis are made between the testing method of the soft and residual soil and the field case, so as to set up the testing method which is suitable for use in the field.
