| 摘 要： | 为了求得塑料排水板在不同布置方式和打设密度下土体固结速度的变化规律,对加固模型进行简化,由几何关系确定塑料排水板理论上存在的3种布置方式;根据水的渗透原理确定3种布置方式下单根塑料排水板影响区域形状,并在相同打设密度的前提下计算得出各影响区域边长之间的关系;在给定的计算条件下,推导出3种布置方式下平均固结度计算式。结果表明,梅花形方式布置时在加固后期的固结速度要快于正方形和正六边形方式布置时的固结速度,但在加固早期固结速度却要慢于后2种布置方式下的固结速度。

| Abstract: | In order to obtain the consolidating velocity of soft soil with different disposing modes and different draining densities of the PVDs,firstly,the consolidating models are predigested,the conclusion that the disposing modes of the PVDs only existed three kinds geometrically is proved theoretically.Then,according to the penetrability of water,the influenced scopes of single PVD with three kinds of disposing modes are educed,and the relationship among the lengths of different influencing scopes with the same ... |
