摘要
土体冻胀作用对基坑支护结构的受力影响显著,但目前没有关于地下连续墙的相关研究。文中结合哈尔滨地铁2号线文化宫站地下连续墙现场监测数据,分析了冻土地区土体冻胀作用对地下连续墙变形和支撑轴力的影响程度,并提出了施工建议。
The frost heaving of soil has a significant effect on the stress of foundation pit supporting structure, but there is no relevant research on diaphragm wall at present. Based on the monitoring data of underground diaphragm wall in the Cultural Palace Station of Harbin Metro Line 2, this paper analyses the influence of frost heave on the deformation and supporting axial force of underground diaphragm wall in frozen soil area, and puts forward construction suggestions.
