水库大坝的病险主要集中于漫顶垮坝、坝体或坝基的渗透破坏、建筑物与坝体的接触渗透破坏、坝体滑坡破坏、坝体裂缝和变形破坏以及地震导致的液化或其他形式的垮坝破坏等形式。针对这些病害成因,可以选择不同的除险加固方式,如坝体加高培厚技术、混凝土老化及病害处理技术、坝体与坝基防渗加固技术等。现主要对水库大坝混凝土老化及病害处理技术进行分析论述。 The main risk of the reservoir dam is concentrated in the collapse of the overburden, the infiltration and destruction of the dam body or dam foundation, the contact and infiltration of buildings and the dam body, the landslide damage of the dam body, the crack and deformation of the dam and the liquefaction caused by the earthquake Forms of collapse and other forms of collapse. In view of the causes of these diseases, we can choose different ways of reinforcement and reinforcement, such as increasing the thickness of the dam body thickening technology, concrete aging and disease treatment technology, dam and dam foundation seepage reinforcement technology. Now the main dam concrete aging and disease treatment technology analysis and discussion.
