Differential Settlement and Induced Structural Damage in a Cut-and-Cover Subway Tunnel in a Soft Deposit
Publisher: American Society of Civil Engineers
Abstract: This study investigated the differential settlement and induced structural damage in the west extension of Nanjing Metro Line 1. The minimum and maximum cumulative settlements measured over the course of four years of ...
Three-Dimensional Analytical Model for Coupled Track-Tunnel-Soil System in a Multilayered Half-Space
Publisher: ASCE
Abstract: An analytical model is presented in this paper to predict the three-dimensional dynamic response of a circular tunnel in an elastic multilayered half-space. By applying the transfer matrix method and wave transformation, ...
Modeling of Vehicle-Track-Tunnel-Soil System Considering the Dynamic Interaction between Twin Tunnels in a Poroelastic Half-Space
Publisher: ASCE
Abstract: The vibration prediction of a vehicle-track-tunnel-soil dynamic system is quite meaningful in engineering practice. However, the complexity involved in modeling the underground environment makes most previous studies ignore ...
Effects of Active Axial Force Adjustment of Struts on Support System during Pit Excavation: Experimental Study
Publisher: ASCE
Abstract: Given their high cost, servo steel struts typically are used only in specific sections of foundation pits in which nearby buildings are sensitive to excavation-induced deformation. Servo steel strut adjustments affect the ...
