番禺地区病险水库地质特点及加固对策
摘要:广州市番禺区目前尚在发挥效益的水库有15座,其中12座水库存在病害隐患,急需除险加固。基于工程地质勘察与评估工作,查明了辖区病险库的地质特点:坝身质量较差、坝基存在渗漏及渗透破坏问题、软基沉降变形和饱和砂土地震液化问题等,探讨了整险加固的工程措施,如加高加固大坝、防渗处理、抗地震液化加固等。结果为辖区病险水库整治提供技术支持,对国内类似水利工程整险加固有较好的参考价值。
Abstract:There are 15 reservoirs still yield benefits in Panyu District of Guangzhou City, which 12 reservoirs in danger disease, urgent need for reinforcement. Based on geological survey and assessment work, identification of the area's geological features dangerous reservoirs:dam body of poor quality, dam leakage and infiltration and sabotage the problem exists, soft ground deformation and earthquake liquefaction of saturated sand, etc, of the entire insurance reinforced engineering measures, such as heightening and strengthening dam, seepage control, anti-earthquake liquefaction and so on. The results for the area to provide technical support for remediation dangerous reservoirs, water conservancy project on the whole similar risks internally reinforced with a good reference value.
