抗疏力固化土强度及变形特性的试验研究

摘要

以陇东地区黄土为固化对象，利用抗疏力水剂CONSOLID444（C444）和粉剂 SOLIDRY（SD）作为土壤固化剂，形成抗疏力固化土。通过压缩试验及强度试验，分析了抗疏力固化土的工程特性，结果表明：抗疏力固化剂可显著降低黄土的压缩性，提高黄土的强度。通过对抗疏力工程土与灰土工程特性的对比，表明抗疏力工程土与灰土类似，可作为黄土地基处理的工程材料。%Taking the soil in the east part of Gansu Province as the experimental material ,this study first forms CONSOLID solidified soil by adding CONSOLID stabilizers of water agent CONSOLID 444 (C444 ) and power agent SOLIDRY (SD) .It then tests the CONSOLID solidified soil through the compressive ex-periment and the strength experiment and analyzes its engineering characteristics .The results show that the CONSOLID stabilizer can significantly decrease the deformation of the loess and increase its strength . Compared with the lime soil ,the engineering characteristics of the both kinds of soil are similar to each other .The CONSOLID solidified soil can be the material of foundation treatment .
