和弦搜寻演算法在土石坝渗流破坏中的应用

Application of Chord Search Algorithm in the Earth-rock Dam Seepage Destruction

根据土石坝坝体破坏案例所累积的经验,除坝顶溢流溃决破坏外,坝体渗漏亦为造成管涌破坏主要原因之一。管涌会造成坝体突然、全面的破坏,后果非常严重,本研究最佳化演算法采用和弦搜寻法,分析中以MATLAB作为和弦搜寻最佳化流程的主控伺服,常用的地工分析软体FLAC则扮演计算引擎的角色。以评估本研究所研拟的和弦搜寻演算法应用于土石坝渗流问题诊断的功效,以说明此方法的可行性与有效性。

According to the accumulated experience of earth-rock dam destruction case, in addition to the destruction of crest flood outburst, the dam seepage is also one of the main causes of piping failure. Piping will cause the dam suddenly, comprehensive destruction, and the consequences are very serious. The study of optimization algorithms using chord search method, the analysis with MATLAB as the main control optimized search chord flow servo, commonly used to engineering analysis software FLAC as calculation engine role. Evaluating the proposed of the chord search algorithm used in earth rock dam seepage problem diagnosis function to illustrate the feasibility and effectiveness of this method.
