摘　　要：根据弱膨胀土的变形特征和施工特点,讨论并确定了弱膨胀高填土浅层强夯加固处理的原则和参数设计。结合工程实际,提出了确定夯击能量、夯击次数等主要参数简便易行的工程方法。现场测试结果表明:该方法能在短期内完成浅层填土固结沉降,有效提高地基强度,缩短工期,降低工程造价。According to construction characteristic and the denaturalization feature of weak expansion earth, a design of parameters of weak expansion high fill earth shallow- layer strong ramming and the principle of consolidation treatment are discussed and determined. In accordance with the actual project, a simple, convenient and easy operating method used for determining main parameters such as ramming impact energy and ramming impact frequency, etc. is put forward. Shallow-layer mud consolidation settlement can be realized in a short time by using this method, thus the strength of the foundation is raised effectively, the allotted time of a project is shortened and the cost is reduced.
