摘　　要：以运维数据为基础,分析了广州中心城区堤防出现周期性陷坑的主要原因,对防治陷坑的多种工程和非工程治理措施的有效性进行了评估。结果表明,高强度降雨是造成陷坑的主要原因,填充泡沫胶、铺设土工布+反滤排水、冲水密实等措施的应用使得堤防陷坑数量呈现明显的下降趋势,有效降低了堤防出现陷坑的风险,提高了堤防安全运行水平。Based on the operation and maintenance data,this paper analyzes the main reasons for the periodic sinkholes in the dikes in the central city of Guangzhou,and evaluates the effectiveness of various engineering and non-engineering measures to prevent the sinkholes.The results show that high-intensity rainfall is the main cause of sinkholes.The application of foam rubber filling,geotextile laying+filter drainage,and flushing water compaction have made the number of dike sinkholes show a significant downward trend,effectively reducing the occurrence of sinkholes in the embankment and improved the level of safe operation of embankment.
