摘要:
黄土地基的湿陷性是造成建筑物安全的重要隐患,需完全消除或部分消除.PHC管柱在群桩的静压连续贯入过程中,易引起桩周土体的挤密效应和相关物理力学特性的变化.通过河南省三门峡市某湿陷性黄土地基中PHC管桩施工前后,对场地土进行物理特性(干重度和孔隙比)试验和湿陷性分析试验,发现PHC管桩的静压贯入会使桩周黄土的密实度增大,能降低或消除黄土的湿陷性.
Abstract:
The collapsibility of loess foundation is a potential danger for the buildings safety,and it needs com-pletely or partly eliminating. The PHC pipe pile would arouse the compaction effect and relevant mechanicalcharacters of the soil around the piles during the successive penetrating process of pile group. This paper basedon the PHC pipe piles before and after construction,used in collapsible loess foundation of the Sanmenxia city ,Henan province ,the physical property and collapsible analysis for the soil shows that penetrating process of pilegroup can make the densities of the foundation soil rise , reducing or eliminating the collapsibility of loess.
