| 摘 要： | 为适应不同工程对地基土强度和变形的要求,采用水泥、石灰、粉煤灰和SH固土剂等单独或联合固化盐渍土.通过抗压强度实验得到了6种固化土的轴向应力应变曲线.总体上,石灰+粉煤灰固化土应力应变曲线的塑性屈服阶段较长;水泥+石灰固化土的早期强度较高,弹性变形阶段曲线的斜率较大;掺加SH固土剂使固化土的强度和水稳性得到增强、塑性屈服阶段延长.SH固土剂+石灰+粉煤灰固化土的强度高且弹塑性优良,既能适应公路交通载荷作用;又因填料较轻,还可减少地基的沉降量.

| Abstract: | In order to overcome the effect from water absorbing property of saline soil inshore,it is proposed to solidify the saline soil with cement,lime,fly ash and polymer SH agent for different engineering purposes.The vertical stress-stain curves of six solidified saline soils are obtained using unconfined compressive strength test.There is a long plastic yield section in the curve of solidified soil with lime and fly ash.There is a higher strength and a steeper slope at the elastic deformation section in the cu... |
