摘要
基于渗透力概念在管涌问题研究中的具体应用,按照渗透力与土颗粒浮重间的极限平衡推导出能计算管涌土的砂砾土料各级大小土颗粒的管涌临界坡降公式,并经过国内外大量管涌试验资料的验证是合理可信的。
The practical application of seepage force concept to the piping problem research is described. According to the limit equilibrium between seepage force and buoyant weight of soil grains, the formulas to compute piping critical gradient for various grain sizes in sandy gravels of piping soil are derived. And then they are verified by many data of piping experiments; it is shown that these formulas are reasonable and responsible.
