| 摘 要： | 冰体融化后,包裹在冰川体内的碎屑物质直接堆积沉积称冰碛土,其特点是无层序,无分选,块石、砾石、砂及粘性土杂乱堆积,常具架空结构,力学性质差异大.本文以康定机场土石方试验段工程为例,将冰碛土地基可分为块石架空区、受地下水影响区和不受地下水影响区,按不同分区采取不同能级的强夯或碾压处理,以消除架空结构,提高地基土密实度.

| Abstract: | Taking the Kangdi airport as an example, the moraine soil characteristics and reinforcement methods are discussed in this paper. Moraine soil has plenty of large block stone, bad gradation, significant differential parameters and framing structure. The moraine soil ground is divided into framing layer, macadam layer affected or unaffected by underground water. Thus its reinforcement methods are suggested as dynamic consolidation and rolling compaction to decrease its void volume and increase its density. |
