我国相当多的地区均分布有粉土。近年来,我国沿江、沿海一带高速公路建设迅速发展,高速公路的填方工程量又很大,带动了粉土研究工作。针对粉土路基填筑技术在施工技术上的研究不足,从粉土的物理力学特性出发,概述了粉土的工程特性、压实标准以及压实机理。 A considerable number of areas in our country have silt distributed. In recent years, the construction of expressways along the Yangtze River and along the coast of our country has been developing rapidly. The filling amount of expressways has been very large, which has led to the research work on silt. In view of the lack of research on construction technology of silt subgrade filling technology, the engineering characteristics, compaction standards and compaction mechanism of silt are summarized from the physical and mechanical properties of silt.
