砂石垫层料的工程特性及施工中应注意的问题

Engineering characteristics of sand and gravel bedding material and concerns in construction

对无粘性粗颗粒土多年的试验研究表明 ,采用粗粒土作砂石垫层是高层建筑地基处理的一种方法。总结了多年的应用实践 ,对砂石垫层的作用、砂石垫层料的工程特性。

The test research on non coherent coarse grain soil for years indicates that coarse grain soil can be used as sand and gravel bedding layers for high building foundation treatment. The paper summarizes the application practice for years and gives systematic description of the role of sand and gravel bedding layers, engineering characteristics of bedding material, concerns in selection and construction and general method of construction quality monitoring.
