公路土的工程分类问题不仅是分类体系本身的问题,而且与分类标准、试验方法以及工程设计、施工等的关系极为密切。合理的分类,可以大致判定土的工程特性,确定土的研究方法和内容,所以它是研究一切土工问题的基础。近年来,作者针对《公路土工试验规程》(JTJ-051-81)土分类中所存在的问题,又进行了修订,现将修订土分类时的依 The problem of engineering classification of highway soil is not only a problem of the classification system itself, but also has a close relationship with classification standards, test methods, and engineering design and construction. Reasonable classification can roughly determine the engineering characteristics of soil and determine the research method and content of soil, so it is the basis for studying all geotechnical problems. In recent years, the author has revised the existing problems in the “Territory of Highway Geotechnical Engineering Tests” (JTJ-051-81) classification, and will now revise the
