排水砂井除排水作用外，还起到竖向加筋抗滑作用。
Packed drains also have a vertical reinforcement and anti slide effect besides the drainage.
竖向排水体包括砂井和塑料排水板已广泛应用于加速软黏土地基的固结。
Vertical drains including sand Wells and prefabricated drains have been widely used to accelerate the consolidation of the ground consisting of soft clays.
经过排水固结法的经济分析及软土排水固结过程中的强度分析，提出了砂井参数及加载计划(工期)的优化设计方法。
By Analyzing the economy for consolidation and the strength of soft clay during consolidation, the optimal design of the parameters of sand well and the loading schedule (project term) is proposed.
探讨了单一砂井双面排水情况下软土地基的平均固结度计算方法，提出了固结度计算的新的修正方法，对软土地基内路基设计具有一定的指导意义。
The calculation method of average sand drain and the new modified method are discussed. The results can serve as a guide to subgrade design of soft ground.
