Abstract Building settlement control, especially non-uniform settlement control, is the key difficulty during shallow-buried tunnel construction. Aiming at the poor self-stability of sandy cobble stratum and its susceptibility to partial collapse, this paper presents the settlement control standard and a reasonable ground consolidation plan and excavation method for the construction of a shallow-buried tunnel in sandy cobble stratum that passes under buildings based on construction of a test section. The monitoring results show that the building settlement is effectively controlled and safety is guaranteed thanks to the settlement control mentioned above.
Abstract：
Building settlement control, especially non-uniform settlement control, is the key difficulty during shallow-buried tunnel construction. Aiming at the poor self-stability of sandy cobble stratum and its susceptibility to partial collapse, this paper presents the settlement control standard and a reasonable ground consolidation plan and excavation method for the construction of a shallow-buried tunnel in sandy cobble stratum that passes under buildings based on construction of a test section. The monitoring results show that the building settlement is effectively controlled and safety is guaranteed thanks to the settlement control mentioned above.
