摘要
结合南京聚宝山公园一期工程地基处理的实例,介绍采用强夯法处理大面积杂填土地基的设计方法。重点阐述采用强夯法处理地基时,如何根据工程实际地质情况合理的确定强夯法的有效加固深度、夯击能量、夯击遍数、夯击点布置形式及夯击点间距。针对强夯法施工效果检验和测试试验数据,对加固效果进行了分析和评价,表明强夯法进行地基处理能取得良好的社会和经济效益。
Combining with the actual case of foundation treatment of the first phase project of Jvbaoshan Mountains Park in Nanjing, the design method of dynamic compaction for the miscellaneous fill soil foundation strengthening was introduce. How to determine the effective reinforcement depth, compaction energy, the number of compaction times, arrangement form of tamping point, and the tamping point spacing reasonably according to the actual geological conditions of the project was expounded emphatically when using dynamic compaction treating the foundation. In addition, the test method of examining and testing the construction effect by dynamic compaction. According to the test data, the strengthening effect was analyzed and evaluated. It was indicated that social and economic benefit can be obtained by dynamic compaction treating the foundation.
