湿陷性黄土地区结构设计探讨

Structural Analysis and Calculation in Collapsible Loess Regions

湿陷性黄土普遍存在于北方地区,其物理力学比较特殊,遇水浸湿时,土的力学强度显著降低,同时产生湿陷变形,对建筑物危害较大。针对某场区大厚度湿陷性黄土地基、Ⅳ级湿陷性条件下,论文论述了新建建筑物、构筑物的湿陷性处理方案,并从地基处理、结构设计、防水设计、施工措施、使用及维护等角度进行了相应设计。

Collapsible loess are generally exists in the north region,when the soil is soaked with water,the mechanical strength of the soil decreases significantly,and collapsibility deformation occurs at the same time,which is a great harm to buildings due to this special physical mechanics.This paper discusses the collapsibility treatment scheme of new buildings and structures under the condition of large thickness of collapsible loess foundation and Class IV collapsibility,and the corresponding design is carried out from the perspective of foundation treatment,structural design,waterproof design,construction measures,use and maintenance.
