中文摘要：

总结采用爆炸处理软基的防波堤、护岸已建工程的常见堤身断面形式,结合工程实例,对堤身整体失稳和局部失稳这两种失稳形式及其原因进行分析,并探讨在设计和施工过程中保证堤身稳定的措施,认为确保堤身落底达到设计高程和完整形成堤侧水下平台是防止堤身产生失稳破坏的关键,合理的施工方法与施工过程控制是堤身稳定的重要保证。

英文摘要：

This paper summarizes common sections of the breakwater and revetment on soft ground treated by explosive compaction,analyzes two kinds of instability forms,i.e.overall instability and local instability,together with the causes,and discusses measures ensuring the stability of the breakwater from both design and construction.It is concluded that it’s crucial to ensure the breakwater to fall to the design elevation and form complete underwater platform for preventing the breakwater’s instability,while suitable construction method and process controlling are important guarantees of the stability.
