摘　　要：室内土工试验,是一项重复性较高而又复杂、细致的试验活动,所得出试验数据的准确性,既是研究工作的基础之一,又直接关系到设计计算的可靠性和施工的工程质量。特别是低强度、易扰动的软土,试验数据的准确性尤显重要。结合京津塘、淮盐、连徐等多条高速公路的软土路基,就软土试验中的准确性进行分析,对软土剪切试验、固结试验和泥炭土试验中的一些规律和试验重点做一些介绍。望能对专业人士有所借鉴。Indoor geotechnical test, as a complex and meticulous activity with high reproducibility and accurate test data, not only is one of research basis, but also relates to reliability of design calculation and quality of engineering construction directly. For soft soil with low strength and easy to be disturbed especially, accuracy of the test data is most important. Combining with the soft soil subgrade of Beijing-Tianjin-Tanggu, Huaian-Yancheng, Lianyungang-Xuzhou Highway, the accuracy in the soft soil test was analyzed and some laws and test focuses in the soft soil shear test, consolidation test and peat soil test were introduced, which are expected to be helpful to professionals.
