摘　　要：在地质情况复杂、土层起伏很大的湿陷性黄土场地,当建筑物变形控制要求较高,需全部消除场地湿陷性时,可采用不同夯击能进行强夯;当建筑物变形控制要求不高,仅需消除基础范围内的全部湿陷和基础范围外部分消除湿陷性时,可通过强夯消除室内地面的部分湿陷,采用强夯和挤密联合法完全消除基础下的地基土湿陷。通过方案对比,分析了两种方案的特点及其适用范围,结合实际工程可知,应调整湿陷性黄土含水量,以取得最佳的强夯效果。On the collapsible loess foundation with complicated geological conditions and rugged terrain, when the deformation control, requirement of the building is severe, different tamping energy can be adopted for dynamic consolidation to eliminate collapsibility completely; when the deformation foundation requirement of the building is not too severe, which needs to eliminate collapsibility of the under the base completely and eliminate collapsibility of other areas partly. Dynamic consolidation technique can be adopted to partly eliminate collapsibility of indoor floor while dynamic consoildation and ground compaction method can be adopted. The characteristics and scope of application of these two kinds of schemes could be analyzed through comparison, and by combining with practical engineering, the water content of collapsible loess could be adjusted to get the best compaction effect.
