Probabilistic and deterministic analyses are used by the authors to estimate the ground movements induced by tunnelling. The deterministic model was simulated by FLAC3D. WebJul 26, 2024 · A new concept called the transmission ratio of ground volume loss (TRGVL) is proposed to describe the variation law of ground volume loss with depth above the tunnel. Based on the developed Gaussian function, the formula for TRGVL is deduced. Further, the first-order derivative of TRGVL is presented to evaluate the dilation and …

WebNov 27, 2024 · Tunnel construction induces soil movement and imposes lateral load on existing buildings closer to tunnelling, and it may cause displacement, rotation, overturning, and settlement of the pile. The interaction between the ground and a tunnel under construction is three-dimensional problems, and modelling the influence of tunnel is only … WebMar 28, 2024 · It is assumed that the disturbance boundary of the tunnel is a circular arc surface, the disturbed soil is divided into multiple slices, and the sliding force and resistance on the circular arc are obtained through a stress analysis of the slices. WebNov 1, 2024 · In this paper, the author performed two centrifuge model tests at the University of Science and Technology of Hong Kong for two cases where the tunnel was located at cover over diameter (C/D) of 1.5 and 3.3 to investigate the passive failure and deformation mechanism due to tunneling in two-layer soils, sand and clay.
