摘要
结合浙江东部沿海堤塘安全分析的一个实例,分析雨水或越浪量下渗对海堤稳定的影响,并通过饱和非饱和/非稳定渗流分析数学模型开展堤身不同土饱和度对海堤渗流稳定的影响分析,分析显示海堤土的初始饱和度对海堤渗流影响大,初始饱和度大的海堤在高潮位作用下可以很快形成较高较陡的浸润线,当堤身土体防渗性能差时很容易造成渗透破坏.
The impact of rain and overtopping flow infiltration on seawall stability is discussed in the paper based on eastern Zhejiang coastal safety analysis. The influence of different soil saturation on seawall stability is also analyzed by saturated or unsaturated/unsteady seepage mathematical model.The analysis illustrates that the initial saturation of the levees has great impact on seawall seepage.The seawall with high initial saturation tends to form higher and steeper saturation line and to cause seepage when the poor seepage-proofing performance of the levees occurs.
