( 3 ) from soil mechanical properties improving mechanism , combined with the difference of different organic matter content and mechanical properties deeply discussed the mechanism of solidification , built the relationship of macro mechanical properties and micro - mechanism ( 3 )从土的基本性质改善和有机质影响的基本原理出发,结合试验当中不同有机质含量固化土力学性质的差异对固化机理进行了深入的探讨,建立了力学性质与微观机理之间的联系。
