摘要

在不排水循环荷载作用下,超孔隙压力增大,导致软土有效应力降低,进而可能发生破坏。竖向排水管的径向排水管使循环加载时的超压迅速消散,从而避免了地基土的破坏。本研究的目的是对长期快速循环荷载作用下,垂直排水渠径向流固结下无涂抹的软粘性沉积物进行分析封闭研究。利用Green建立了循环荷载作用下含固结度孔隙压力的数学表达式

An analytical model for radial consolidation prediction under cyclic loading
The excess pore pressure increases under undrained cyclic loading which cause decrease in effective stress followed by possible failure in the soft soil. With the inclusion of vertical drains radial drainage allows quick dissipation of excess pressure during cyclic loading and thereby failure of foundation soil may be avoided. The present study aims for analytical closed-form investigation on soft cohesive deposit under radial flow consolidation through vertical drains with no smear when subjected to long-term rapid cyclic loading. The mathematical formulation of pore pressure including degree of consolidation under cyclic loading is developed by using Green
