浑水淤积层的防渗性能分析

浑水中含有较多的细小颗粒,在水库渗漏过程中,泥沙逐渐沉积、下渗,在库底形成一弱透水的淤积层,且浑水入渗对库底地层起到充填挤压、渗透固结和改良作用,提高原地层的密实度,降低库盆的渗漏。经对多个水库的实例分析研究表明:一定厚度的浑水淤积层,能够改善库底地层结构,提高抗渗透能力,减小渗漏量,可作为提高库底抗渗性能的工程措施。

Investigation and analysis of seepage prevention property in the sediment deposition

There are many fine and small particles in the siltwater.In the seepage process of the reservoir,the silts will be sediment,infileration to form a sediment doposition with small permeable in the bottom of the reservoir: Also when the silt water was enfiltrated into bottem of reservoir,it can play the functions of filling,squeezing and pressing,percolate consolidation and improving to inerease the density of the sediment deposition and reduce the seepage.Through the real case investigation for the seepage pr...
