摘要
斜交出洞的隧道明洞往往出现基础较深或承载力不足的现象,提出了处理此类问题的半基岩半桩基混合基础方案,并将其应用到东峪隧道出口段的明洞基础中,通过有限元结构计算,验证了该混合基础明洞的稳定性。
The problems of deep foundation and insufficiency of bearing capacity are always found in cut-and-cover tunnel in the zone of the slope adjacent to mountain. For the problems, a composite foundation structure is put forward and the application in Dongyu Cut-and-Cover Tunnel is introduced. Through FEM method, the stability of composite foundation of cut-and-cover tunnel is validated.
