摘　　要：海港工程中,常利用临时土石坝阻隔海水,保证坝体内部干施工的顺利进行,因此土石坝的稳定性和安全性对海港工程的施工质量和经济效益具有重要影响。针对土石坝风险的特点,将土石坝监测和风险分析理论相结合,提出利用风险的评估结果指导监测工作,对监测数据进行系统分类和分析,判断运行过程中的风险状态,并指导风险控制的实施,最终使土石坝的稳定性和安全性得到保障。结合工程实例,对风险分析理论在土石坝监测中的应用进行了说明,并验证了该方法的可行性。In some harbor construction,the temporary earth-rockfill dam was applied to keep the water out to ensure the successful construction.The stability and safety of earth-rockfill dam has important impact on the construction quality and economic benefit of harbor engineering.Base on the risk characteristics of the earth-rockfill dam,with the combination of the monitoring and risk analysis,the monitoring of the dam is carried out using the risk assessment of the earthrockfill dam.With the analysis of the monitoring data,the measure of the risk control was executed effectively.Based on this method,the stability and safety of the earth-rockfill dam is guaranteed.Combined with engineering example,this method was illustrated in detail and the feasibility of the method was verified.
