In accordance with the construction of xi ' ning - huangyuan first class highway and machangyuan - ping ' an high - speed highway , based on a good deal of investigation , this paper studies the geologic character and the main physical mechanics of the collapsibility loess in qinghai . this paper also studies the foundation treatment effect with dynamic consolidation , impact rolling , lime pile and lime - soil cushion . to dynamic consolidation , much attention is given to the relationship between the ramming energy and the effective depth 本文结合西湟一级公路、马平高速公路建设，对青海地区湿陷性黄土进行了大量勘探调查，总结研究了青海地区湿陷性黄土的地质结构特点、主要的物理力学性质及其规律；并通过现场试验，系统地研究了强夯、冲击碾压、灰土挤密桩和灰土换填等地基处理方法的施工工艺及处理效果。
