Cipancuh大坝是印度尼西亚最古老的水坝之一,位于印度尼西亚西爪哇省南安由地区的Cipancuh河上。作为一座老坝,大坝(包括土坝和附属建筑物)承受着由于气候条件导致的恶化。另一个需要注意的重要事项是,流域条件的变化引起了水流特性的极端变化。基于沉积率的计算,预测大坝服役年限仍有81年,因此必须对大坝加以维护。大坝下游有一小城镇,人口约20万,若大坝管理不当,下游人民的生命财产安全将受到严重威胁。根据这项研究,Cipancuh大坝被评定为高风险大坝。大坝的维护包括:维修坝体、维修配套建筑物、加大溢洪道泄洪能力、安装新的监测仪器以及使用现有技术加强监测等。总之,有必要改善大坝性能以提高大坝的安全性。
Cipancuh Dam is one of Indonesia’s oldest dams, located on the Cipancuh River in the Nam-On Area of West Java, Indonesia. As an old dam, dams (including earthworks and ancillary buildings) are subject to deterioration due to climatic conditions. Another important thing to note is that changes in watershed conditions cause extreme changes in water flow characteristics. Based on the calculation of sedimentation rate, it is estimated that the dam service life is still 81 years, so the dam must be maintained. There is a small town downstream of the dam with a population of about 200,000. If the dam is not properly managed, life and property safety of the downstream people will be seriously threatened. According to the study, Cipancuh Dam was rated as a high-risk dam. Dam maintenance includes: maintenance of dams, maintenance of ancillary buildings, expansion of flood spillway capacity, installation of new monitoring instruments and use of existing technologies to enhance monitoring. In summary, there is a need to improve dam performance to improve dam safety.
