| 摘 要： | 德泽水库大坝为混凝土面板堆石坝，大坝的趾板建在弱风化岩基上，趾板采用C30W12F200混凝土，趾板在浇筑完成后经检查共发现有62条裂缝，总长度达169.64 m。为了对裂缝进行有效地处理，详细分析了产生裂缝的原因，并针对不同类型的裂缝采取不同的处理措施，如Ⅰ类裂缝用化学粘补材料进行修补，Ⅱ类裂缝采取先环氧砂浆钻孔灌浆、再粘补表面的方法修补。所有裂缝经处理后，均达到防渗设计要求。

| Abstract: | The toe slab of the concrete faced rockfill dam(CFRD) of Deze Reservoir,using the concrete C30W12F200,is built on weakly weathered rock foundation.After grouting,62 cracks were found on toe slab with a total length of 169.4 m.To treat these cracks,their causes were analyzed and different treatment measures were adopted for different crack types;for type I crack,chemical bonding material was used for concrete patching;for type II cracks,epoxy mortar was used for drilling grouting and then the surface was patched by bonding material.The seepage prevention effect is satisfying after the treatment. |
