大连港大窑湾港区三期工程地基处理

Ground Improvement for Dayaowan Port Area Phase Ⅲ Project of Dalian Port

针对大连港大窑湾港区三期工程工期紧、陆域形成方式较为复杂的工程特点,堆场区分别采用了振冲置换加强夯法、真空联合堆载预压法和强夯法进行地基处理,而场桥轨道梁区采用了预制桩、锥型锤强夯等地基处理设计方案,可为类似工程设计提供参考。

In the light of the engineering characteristics of Dayaowan Port Area Phase Ⅲ Project of Dalian Port, i.e., pressing construction period and complicated land formation scheme, vibro-floatation combined with dynamic compaction, vacuum combined with surcharge preloading, and dynamic compaction were adopted for the ground under the storage yard; and precast piles and dynamic compaction with cone hammers were applied for the ground under the rail bearer of gantry crane. The engineering experience may serve as a reference for similar engineering design.
