摘要
坝体稳定是大坝安全运行的基本保证,而扬压力是体现坝体稳定的一个重要指标,研究确保扬压力满足设计指标的可行措施是重点。针对混凝土大坝坝基渗压系数超过设计值的问题,分析确定采取新增测压管和排水孔的方式,解决扬压力超限的问题,提供一个分析、处理、解决问题的参考案例。
Dam body stability is the basic guarantee for safe operation of the dam, and uplift pressure is an important indicator to reflect the stability of the dam body. The key point is to study the feasible measures to ensure that the uplift pressure meets the design index. In order to solve the problem that the seepage coefficient of concrete dam foundation exceeds the design value, a new pressure measuring pipe and drainage hole are adopted to solve the problem of excessive uplift pressure, providing a reference case for analysis, treatment and solution.
