湿陷性黄土地质结构不稳定,为地上建筑提供的支撑力较为有限,需要利用有效手段对其进行负荷地基强化才能够达到有效控制沉降与变形的效果.本文以此为研究目标,在分析湿陷性黄土地质特征的基础上,以挤密桩为主要施工工艺,分析应用优势、梳理应用流程、明确工艺参数,并利用具体的工程实例探讨挤密桩施工下的地基沉降变形特性,旨在为后续工程实践提供参考.
Study on the Settlement and Deformation Characteristics of Compacted Pile Composite Foundation in Collapsible Loess Areas
The geological structure of collapsible loess is unstable,and the support provided for above-ground buildings is relatively limited.Therefore,it is necessary to use effective means to strengthen the load-bearing foundation to achieve effective control of settlement and deformation.Based on this research objective,this article analyzes the geological characteristics of collapsible loess,uses compacted piles as the main construction technique,analyzes application advantages,reviews application processes,defines process parameters,and deformation characteristics of the foundation under compacted piles using specific engineering examples,and to provide reference for subsequent engineering practice.
