摘　　要：以某工程厚层含淤泥新杂填土地基强夯法处理为例,根据试夯施工研究,提出了采用夯前预压,先轻后重,逐渐加能的强夯加固工艺,并根据强夯后质量检测以及工后长期观测资料对强夯法处理新杂填土地基的效果进行了分析,对强夯加固后的地基承载力、有效加固深度进行了评价。According to the example of a project of heavy tamping treatment for foundation with a thick layer of recently deposited miscellaneous fill containing mud,a consolidation method of “precompression before tamping”is presented:the tamping is light first and then becomes weightier and weightier with energy gradually added. The article analyses the effect of heavy tamping treatment of foundation of recently deposited miscellaneous fill on the basis of the quality test after heavy tamping and long-term survey after constructing. And the foundation bear capacity after heavy tamping and effective treatment depth of heavy tamping are then evaluated.
