为解决滨海盐渍土的低强度和大变形问题,采用水泥、石灰、SH固土剂固化盐渍土,研究含盐量、固化材料掺量、养护龄期和浸泡用水对固化土抗压强度的影响。结果证实:含盐量大于1%,固化土抗压强度随含盐量的增加而减小;掺加水泥、石灰、SH固土剂均可提高土的强度和水稳性;随养护龄期的增加,固化土的抗压强度增加;石灰固化土和SH固土剂+水泥+石灰固化土浸泡海水的抗压强度均小于浸泡自来水的抗压强度。SH固土剂+水泥+石灰的固化土最适宜填筑路堤。
In order to solve the problem of low strength and large deformation of coastal saline soil, the effects of salt content, curing material content, curing age and immersion water on the compressive strength Impact. The results show that: the salt content is more than 1%, the compressive strength of cured soil decreases with the increase of salinity; the strength and water stability of soil can be increased by adding cement, lime and SH agent; , And the compressive strength of cured soil increased. The compressive strength of soaked seawater with lime-cured soil and SH-earthing agent + cement + lime-cured soil were all less than that of immersed tap water. SH soil agent + cement + lime soil most suitable filling embankment.
