土石坝存在的主要病害及防治对策

On Assessment of Ageing Damage of Earth Dam and Countermeasures

截至2006年年底,中国已建的水库8.7万余座。中国现有水库90%以上为土石坝,由于缺乏经验,有许多工程防洪标准低,施工质量差,运行管理跟不上,以致使大多数的土石坝存在不同程度的安全隐患,甚至影响水库的正常运行,成为病险水库。论文分析土石坝存在的问题,提出了必要的加固措施,为水库管理提供科学依据。

More than 87.000 reservoirs,90%of which were of earth dam,had been built in China by the end of2006.Many of them are now becoming devastated and dangerous reservoirs that are unable to operate well because of fissures,seepage,earth creep,devastated slope protection caused by lower quality of construction,poor management and animals.The paper,based on investigation and analysis on the information from checking and supervising earth dams,analyzes main problems and puts forwards corresponding measures for scientific management of reservoirs.
