摘要
在隧道开挖过程中,土体与建筑物的相互作用是一个极其复杂的过程.目前,对建筑物在开挖条件下的变形研究较少.由于建筑结构自身的刚度,其变形曲线与天然地层的沉降曲线有较大的差别.首先,分析建筑物刚度对沉降曲线形状的影响,通过建筑物沉降曲线与天然地面沉降曲线的对比分析,建立适用于建筑物的沉降曲线公式,从而可以初步估算建筑物的变形.然后通过青岛地区的工程实例验证结构刚度对建筑物变形的影响.
In the tunnel excavation process, the interaction between soil and buildings is an extremely complex process. At present, the studies of building deformation under the condi- tions of excavation are less. Because of the structural stiffness, there are large differences between building deformation curve and natural ground subsidence curve. Firstly, the impact of building stiffness on settlement curve shape is analyzed. Through the contrast and analysis of building subsidence curve and natural ground subsidence curve, the settlement of curve formula for building is established, thus, the deformation of building can be preliminarily estimated. Then, the impact of structural stiffness on building deformation is verified by the project in Qingdao.
