深层搅拌桩新型胶结材料的试验研究

Testing Study on a New Type of Agent Applied in Deep Mixing Columns

介绍了一种利用工业废料加工的深层搅拌桩新型土体胶结剂,并将工业废料加固土的无侧限抗压强度、渗透系数、压缩模量、三轴抗剪强度的试验结果以及静载荷试验结果与水泥加固土进行了对比分析.结果发现:工业废料加固土与水泥加固土具有同样的工程性质.另外,还给出了工业废料加固土无侧限抗压强度随时间增长的关系表达式。

A new type of soil strengthened agent sourced mainly from industrial wastes was presented. The physical parameters of its strengthened soils, including unconfined compression strength, coefficient of permeability, compressive modulus, cohesion, angle of internal friction and the strength of static load test were compared with those of cement soil. Moreover, two expressions of anticipating the unconfined compression strength of the strengthened soils were presented, and the strengthening mechanism of the new agent was discussed.
