江苏徐宿地区粉土的基本特性及加固方法研究

Study of stabilized silt in Xu-Su area

对江苏徐宿地区的粉土进行试验研究,发现该地区粉土具有弱可塑性、低粘结性、高分散性及强度较小等特征。通过对石灰、石灰+水泥和 SEU-2 型固化剂稳定该地区粉土进行无侧限抗压强度试验及干缩性能试验研究,认为采用 SEU-2 型固化剂稳定效果较好。

The test study on the silt of Xu-Su district in Jiangsu Province has been carried out. The results show that the silt of this area is of weak plasticity, low cohesiveness, high dispersion and low strength. The lime, cement adding lime, and stabilizer SEU-2 have been used to stabilize the silt respectively. The data of unconfined compression strength and dry-shrinkage tests show that the stabilizing effect of the stabilizer SEU-2 is the best one.
