透水管桩单桩排水特性有限元分析
Finite Element Analysis of Drainage Characteristics of Single Perforated Pipe Pile
摘要: 透水管桩开孔数量通过改变排水通道的密度和渗流路径，加速了土体超孔压消散速率，影响土体内部的压力梯度分布：单孔模型表现出强烈的局部高梯度集中，而多孔结构通过构建均匀的水平渗流场，有效降低了梯度峰值并提升了孔压消散的均匀性。其固结度随时间呈非线性增长，开孔数量越多，固结速率越快，且初期效应尤为显著；增加开孔数量可有效缩短达到目标固结度的时间。
Abstract: The number of openings in perforated pipe piles alters the density of drainage channels and seepage paths, accelerating the dissipation rate of soil excess pore water pressure and influencing the distribution of internal pressure gradients. The single-hole model exhibits strong local high-gradient concentration, while the multi-hole structure effectively reduces gradient peaks and enhances the uniformity of pore water pressure dissipation by constructing a uniform horizontal seepage field. The degree of soil consolidation shows nonlinear growth over time: the greater the number of openings, the faster the consolidation rate—especially significant in the initial stage—and increasing the number of openings can effectively shorten the time required to reach the target consolidation degree.
