摘要
在钢渣的力学特性试验基础上,得到了其抗剪强度、抗压强度和钢渣混凝土水灰比试验的单轴抗压强度值。并分别从钢渣自凝前、自凝后两个方面对钢渣柱复合地基的作用机理进行了研究。结果表明,钢渣桩复合地基作用机理类似于碎石桩和水泥土搅拌柱复合地基,其加固软土地基效果明显。
Composite foundation of steel-ash pile is a new type method of ground improvement. On the basis of testing mechanics special property of steel-ash, the values of shear strength and compressive strength as well as single axial compressive strength were obtained in the paper. Action mechanism of steel-ash composite foundation were studied before and after self-coagulating. It is concluded that composite foundation of steel ash pile is similar to gravel pile composite foundation and deep mixing method of cement soil,and is effective in the improvement of soft foundation.
