Influence of disturbance degree on the propped excavation stability in sandy soil in Shenyang, China
Publikováno v:
Underground Space, Vol 10, Iss , Pp 150-165 (2023)
The stability of deep excavation is often investigated through numerical simulation. However, most constitutive models cannot take into account the influence of disturbance on soil response, especially for excavations in sandy soils. In this study, t

To address the inadequacies of traditional pipe-roof methods, the steel support cutting pipe method (SSCP)—a novel pipe-roof method that improves construction security and underground space usage—is proposed. To further explore the applications o

The excavation of a foundation pit will break the original stress balance and affect the surface settlement of the natural foundation of adjacent buildings, so deformation control is very important. In this paper, numerical simulation results of the
