摘要
利用电离子土壤固化剂 (IonicSoilStabilizer ,简称ISS)、石灰和水泥加固广州吉山粉土质砂 (SM ) ,通过对不同配比、不同闷料时间的击实试验和无侧限抗压强度试验结果进行分析 ,探讨ISS加固土压实性能和强度的变化规律 .结果表明ISS加固土的最大干密度随闷料时间的增长而增大 ,从而可以增大其承载力 ;加固土含水量对干密度的影响因固化剂而异 .建立了ISS加固土最大干密度与闷料时间、ISS石灰加固土强度与压实度的关系式 .
Ionic soil stabilizer (ISS),lime and cement were used to reinforce the silty sand in Jishan,Guangzhou. The compactibility variation and the strength variation of ISS strengthening soil were analyzed by the results of compaction test and unconfined compressive strength test with different proportions and enclosing material time periods. The analytical results indicate that the maximum dry density of ISS strengthening soil increases with the enclosing material time periods,which causes the improvement of bearing capacity,while the effect of the water content of strengthening soil on dry density varies with soil consolidation agent. The relation between the maximum dry density and the enclosing material time period,as well as that between the strength and the compaction degree of the strengthening soil was finally established.
