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.
