通过对陕西省延安市新区区域地质构造和场地地层结构及特征的介绍,知悉本场地有厚度和均匀性均差异较大的素填土层,通过对工程场地素填土层厚度、成分及物理力学性质的分析研究和实践证明,强夯法加灰土挤密桩是对该种素填土层一种较好的地基处理方式.
Through the introduction of the regional geological structure and site stratum structure and features in the Yan’an New Area of Shaanxi Province, it is known that there are plain fill layers with different thickness and evenness in this site. By analyzing the thickness, composition and physical Analysis and practice of mechanical properties prove that dynamic compaction plus lime-soil compaction piles is a good foundation treatment for this type of filling layer.
