摘　　要：以处于大厚度湿陷性黄土场地的某学校餐饮楼检测鉴定与加固设计为背景,研究与总结大厚度湿陷性黄土场地既有建筑出现不均匀沉降后的检测鉴定与加固设计。通过对湿陷性黄土场地因浸水出现不均匀沉降的某既有建筑进行检测鉴定、加固设计、设计服务等工作,总结了湿陷性黄土场地既有建筑地基基础采用坑式静压桩进行不均匀沉降所致的隐患治理程序和治理方法,也对静压桩加固的计算方法和局部顶升纠偏设计进行了总结,并归纳形成了若干结论,可为后续类似的工程项目提供借鉴。Based on the detection,identification and reinforcement design of a school catering building located in the large thickness collapsible loess site,the detection identification and reinforcement design of existing buildings in the large thickness collapsible loess site after uneven settlement were studied and summarized.Through detection identification,reinforcement design and design services for an existing building that has uneven settlement due to flooding in a collapsible loess site,the procedures and treatment methods for the hidden trouble caused by uneven settlement of the foundation of the existing building in a collapsible loess site by using pit static pile were summarized.The calculation method of static pressure pile reinforcement and local jacking correction design were also summarized,and some conclusions were concluded,which can provide reference for subsequent similar projects.
