摘要： 通过对塔城市某化工厂场地工程地质条件的分析，明确了该厂地表的第二层黄土和第三层黄土（最深处约为 6 米）局部具有湿陷性。考虑到上层建筑物承载力的要求，需要对此进行处理。通过技术经济评估，优选强夯法处理此湿陷性黄土地基，讨论了强夯法设计参数的确定，主要包括夯击能、夯点击数和含水率等。通过对此项目进行强夯施工及施工后的检验，验证了强夯法的可行性。

Abstract: The subsurface conditions of a chemical factory in Tacheng City, Xingjiang Autonomous Region indicate that the second and third (which has a maximum thickness of 6 meters) layers of loess deposits are collapsible. The foundation soils are required to be improved in order to meet the requirement of the structures. The dynamic compaction technique for the collapsible soil elimination is selected throughout comprehensive ground improvement feasibility study. This paper discusses the determination of the dynamic compaction parameters such as, compaction energy of each drop, number of drops at each point, optimum moisture content of ground to be treated etc. The construction results and the monitoring test results indicate that this method is a successful application in the collapsible loess elimination.
