摘　　要：对小型土坝的破坏机理及维护方法进行了分析,认为许多小型土坝主要是受到波浪的侵蚀、渗流和降雨冲刷等的破坏,针对这些破坏,提出了采用灌浆、护坡、帷幕和排水等工程措施来维护小型土坝。The failure mechanism and remedial methods of small-sized earth dam are analyzed in this paper. It is concluded that these failures are primarily caused by wave erosion, seepage flow and rain scouring. Therefore, some engineering measures , such as grouting, slope revetment , curtain and water drainage , are to be taken to ensure safety of small-sized earth dam.
