坛子口水库大坝下游坝坡回填材料为风化碎石土，筑坝时未碾压，比较松散。为解决下游城市生活用水问题及防洪需要，拟对大坝进行加高。为保证大坝安全，大坝加高前拟对下游坝坡风化碎石层进行加固处理。在水库正常蓄水位下，采用振冲加密的方法对下游坝坡进行了加固处理。大坝加高后未出现沉降或裂缝等现象，加固效果显著。
罈子口水庫大壩下遊壩坡迴填材料為風化碎石土，築壩時未碾壓，比較鬆散。為解決下遊城市生活用水問題及防洪需要，擬對大壩進行加高。為保證大壩安全，大壩加高前擬對下遊壩坡風化碎石層進行加固處理。在水庫正常蓄水位下，採用振遲加密的方法對下遊壩坡進行瞭加固處理。大壩加高後未齣現沉降或裂縫等現象，加固效果顯著。

Weathered gravel soil is adopted for backfilling downstream dam slope of Tanzikou reservoir dam,which is not rolled during dam construction,therefore the soil is looser.The dam will be heightened according to plan in order to solve downstream urban domestic water consumption problem and flood control demand.Downstream dam slope weathered gravel layer will be reinforced before dam heightening in order to ensure dam safety.Vibroflotation compaction method is adopted for reinforcing downstream dam slope under normal water level in the reservoir.Subsidence or cracks and other problems are not discovered after dam heightening,and the reinforcing effect is significant.
