概述土的液限試驗,在土工試驗中占有重要的地位。在“房屋和工業建筑物天然地基設計标准及技术規范”(HNTY 127-55)中,它与塑限試驗配合,以判定粘土类土的分类。因而液限試驗方法与結果的正确与否,將直接关系到基本建設的工程質量。我們从保証質量的观点出發,會进行了一些理論上的探討和試驗方法的比較,茲提出一些资料和意見。 Overview of the liquid limit test of soil, occupies an important position in the soil test. In the “HNTY 127-55 Natural Flooring Design Standards and Technical Specifications for Housing and Industrial Buildings”, it cooperates with the plastic limit test to determine the classification of clay soils. Therefore, whether the liquid limit test method and results are correct or not will directly affect the project quality of capital construction. From the viewpoint of ensuring quality, we will conduct some theoretical discussions and comparisons of experimental methods. We hereby present some information and opinions.
