天津港真空预压加固排水板间距对工期和造价的影响

Influence of the distance of plastic drainage plate upon time and cost in TianJin Port Area improved by vacuum preloading

对于采用排水固结法加固饱和软粘土地基,在理想井的情况下减小排水板间距可有效地缩短固结时间,但是在设计中也要考虑塑料排水板间距对工期和造价的影响.因此,对天津港真空预压法中塑料排水板打设间距设计时应考虑的加固时间及造价进行了分析,并提出相应的处理方法,具有一定的应用价值.

For the saturated soft clay foundation consolidated by the drainage consolidation method, to reduce the distance of plastic drainage plate would effectively shorten the time for consolidation of soil ＇wherever there are ideal wells. However, the distance of plastic drainage plate varies with time and cost. It is suggested that the optimization between the distance of plastic drainage plate, time and cost in TianJin Port area may be practical.
