Abstract

Considering the interaction between the lining and soil, the analytic solutions to the stress function for the soil and lining deformation caused by the excavation are put forward for the shallow and deep tunnels. The applicability of the algorithm for the shallow and deep tunnels is verified by field monitoring data. Furthermore, through the parameter analysis, a comparison study on the variation of the soil and lining response caused by the excavation for the shallow and deep tunnels is conducted. It is observed that for the soil settlement trough with the value of zero, it is a “groove type” for the shallow tunnel, while “horizontal line” for the deep tunnel. The soil horizontal displacement is “butterfly type” for both shallow and deep tunnels. The lining tangential displacement for the shallow tunnel is an “oblique 8-type” with a smaller bottom, while that for the deep tunnel is a normal “oblique 8-type”.

考虑粘土浅埋深和深埋深的盾构隧道地表移动评价

考虑衬砌与土体的相互作用，给出了浅埋和深埋隧道开挖引起土体和衬砌变形的应力函数解析解。通过现场监测数据验证了该算法对浅埋和深埋隧道的适用性。通过参数分析，对比研究了浅埋和深埋隧道开挖对土体和衬砌响应的影响。可以观察到，对于值为0的土体沉降槽，浅埋隧道为“槽型”，深埋隧道为“水平线”。无论是浅埋隧道还是深埋隧道，土体水平位移均为“蝴蝶型”。浅埋隧道衬砌切向位移为底部较小的“斜8”型，深埋隧道衬砌切向位移为正常的“斜8”型。
