一、关於土分类系统的混乱问题正确地应用试验资料来定出合理的道路土壤名称,是土壤颗粒分析工作中重要的和经常的任务之一。根据道路工程的要求,将土分为砾石质土、砂性土和粘性土三大类,其中粘性土和砂性土的分类标准载于中华人民共和国公路工程设计准则修订草案中。这个标准是根据苏联著名土质学家B.B.俄哈勤教授的研究成果,为苏联内务部公路总局1938年所公布采纳的。但须指出,俄哈勤教授在研究土粒的物
First, the confusion on the soil classification system Proper application of test data to determine the proper name of the road soil, soil particle analysis is an important and often one of the tasks. According to the requirements of road engineering, the soil is divided into gravel soil, sandy soil and cohesive soil three categories, of which clay and sand soil classification criteria set out in the People’s Republic of China Highway Engineering Design Guidelines revised draft. This standard is based on the research results of Professor B.B. Oehaqin, a famous Soviet soil scientist, adopted by the General Administration of Civil Service of the Soviet Union in 1938. However, it must be pointed out that Professor Ohaqqin is studying soil particles
