摘要
岭澳水库土坝是一座较高的碾压式土石坝 ,为二级建筑物 .由于施工质量差等原因 ,在其竣工蓄水后 ,坝体渗流量随库水位上升而明显增加 ,浸润线出溢点高 ,明流面积大 ,大坝有渗透破坏的危险 .对该坝采取了劈裂灌浆和高喷灌浆相结合的加固方案 ,在较短的时间内达到防渗加固和消除坝体渗透破坏的目的 .
The dam of Lingao Reservoir is a rolled earth dam with relative height and the secondary importance grade. Due to the construction quality or some other reasons, some problems appeared when it was finished and put into running. The problems included:the seepage increasing violently with rise of the water level,the soaking line being quite high, the area with evident flow being large, and the dam being in a dangerous state. Therefore, the hydraulic cleaving grouting and high pressure grouting were applied as remedy,and a satisfied result was got in short time.The successful experiences in the reinforcement about this dam can provide valuable reference to other engineerings in similar conditions.
