| 摘 要： | 强夯和强夯置换法是经济高效应用广泛的地基处理方法之一，但工程界对强夯与强夯置换的概念理解仍存在很大分歧。值此多个地基处理技术规范修编的机会，有必要对强夯和强夯置换的概念进行澄清。文中首次明确提出了强夯置换区别于强夯的4个条件：有无填料、填料好否、夯锤静接地压力是否大于80 kPa和是否形成密实墩体。同时，根据68项工程或项目实测资料，首次提出了强夯置换墩长度与能级（最高达到18 000 kN•m）的经验关系，并做成表格供工程人员预估置换墩长度时参考

| Abstract: | Dynamic compaction(DC) and dynamic replacement have become generally accepted ground improvement techniques for their simplicity and cost-effectiveness.But conception of DC and dynamic replacement still have a lot of disagreement.On some foundation treatment specification revision of opportunity,it is necessary to improve the dynamic compaction and dynamic compaction replacement concepts of clarification.The distinctions between DC and dynamic replacement are: with or without filler;with or without grained ... |
