在我国城市化的建设进程中,由于城市土地资源紧缺,城市建设正在向纵深方向发展,并呈现出向城市地下空间的高密度开发倾向和趋势,伴随着城市轨道交通的快速进展,紧邻地铁隧道的深基坑工程不断增多,在深基坑工程的开挖和卸载过程中,必然会产生周围地层的扰动现象,在初始应力改变的状态下,需要对地铁隧道的变形控制进行研究,要关注深基坑施工开挖对地铁隧道的影响,从而推进城市建设快速发展。
In the process of urbanization in our country, due to the shortage of urban land resources, the urban construction is developing in the depth direction and shows the tendency and trend of high-density development to urban underground space. With the rapid development of urban rail transit, Deep foundation pit engineering is increasing. During excavation and unloading of deep foundation pit construction, it is bound to produce disturbances of surrounding strata. Under the condition of initial stress changing, it is necessary to study the deformation control of subway tunnels, The impact of excavation of foundation pit on subway tunnels, thus promoting the rapid development of urban construction.
