河道清淤底泥固化材料正交试验研究

Research of river dredging sediment curing materials orthogonal experiment

介绍了河道底泥常用的固化方法,通过无侧限抗压强度的正交试验,研究了水泥、粉煤灰、生石灰、沸石对固化底泥强度的影响规律,试验结果表明,掺入水泥、粉煤灰、生石灰、沸石后,固化底泥的强度得到明显改善,在四种固化剂中,水泥对固化土抗压强度的影响处于主导地位,粉煤灰次之,生石灰和沸石最小。

Introduced the common solidification method of river sediment, through the unconfined compressive strength of the orthogonal experi-ment , cement, fly ash, lime and zeolite was studied the influence law of the strength of solidified sediment. The test results show that the mixed with cement, fly ash, lime, zeolite, the strength of the solidified sediment are obviously improved. In the four types of curing agent, cement effect on compressive strength of solidified soil in a dominant position, the influence of fly ash, lime and zeolite is minimal.
