An Investigation on Longitudinal Surface Subsidence Deformation of Large-Span Undercut Metro Tunnel

Frontiers in Earth Science, 2022
Underground excavation techniques are frequently used in subway stations during the construction of urban rail transit. The current study analyzes and investigates the surface settlement and deformation laws of large-span shallow buried underground ...

Test Study on the Influence of Foundation Pit Excavation on the Surface Settlement of Sandy Soil Natural Foundation of Adjacent Buildings

Buildings, 2023
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.

Tunnel Surface Settlement Forecasting with Ensemble Learning [PDF]

Sustainability, 2019
Ground surface settlement forecasting in the process of tunnel construction is one of the most important techniques towards sustainable city development and preventing serious damages, such as landscape collapse. It is evident that modern artificial intelligence (AI) models, such as artificial neural network, extreme learning machine, and support ...

A Numerical Study of the Effect of Tunneling on Surface Settlement and Existing Buildings [PDF]

International Journal of Engineering, 2021
This study aimed to determine the effect of various influencing parameters such as tunnel diameter (D), depth (H), width (B), length (L), number of floors, and the horizontal distance of the building from the tunnel axis (X), as well as soil properties such as internal friction angle (ϕ), Poisson ratio (υ), modulus of elasticity (E), and cohesion (C ...

Additional Stress of Soil and Surface Settlement during Tunnel Shield Construction

Buildings, 2023
To study the influence of shield excavation on the surrounding soil, and to control the influence of the shield excavation of the subway tunnel on the surface settlement and the deformation of the surrounding buildings, it is necessary to study the ...

Settlement behavior of swimming algal spores on gradient surfaces

Biointerphases, 2006
When surfaces possessing gradients of surface energy are incubated with motile spores from the green seaweed Ulva, the spores attach on the hydrophilic part of the gradient in larger numbers than they do on the hydrophobic part. This result is opposite to the behavior of the spores observed on the homogeneous hydrophobic and hydrophic surfaces.

xperimental investigations on influences of ground loss on earth pressure and settlement of adjecent underground retaining structures

Yantu gongcheng xuebao, 2021
Underground excavations often pass through underground retaining structures on one side or between the structures. In most cases, ground loss will be caused. At present, there are more and more collapses caused by excavation. When the ground loss occurs,
