黄土塬区深厚黄土的工程性质与地基处理——以陇东地区为例

Engineering Nature of Deep and Thick Loess and Foundation Construction in Loess Plateau, Example of Longdong

通过对陇东黄土塬区深厚湿陷性黄土的工程性质及主要物理力学指标的统计分析,提出了整片土垫层法、灰土挤密桩法、强夯法及DDC工法等适宜于本地区湿陷性黄土地基的处理方法,并对其质量控制的关键进行了阐述。

Based on the engineering nature of deep and thick collapsible loess and statistic analysis of main indicators of physical mechanics in Longdong loess plateau, some applicable foundation construction technology in the collapsible loess area, such as lime-soil cushion, lime-soil compaction pile, dynamic compaction and DDC was proposed, and introduced the key point of quality control.
