Analytical solutions to ground settlement induced by ground loss and construction loadings during curved shield tunneling

Journal of Zhejiang University: Science A, 2021
This paper focuses on the ground settlement induced by the construction of a curved shield tunnel. Ground loss and construction loadings are the two factors causing ground settlement, and two corresponding analytical models were developed.

Prediction of ground settlement and the corresponding risk induced by tunneling: An application of rock engineering system paradigm

Tunnelling and Underground Space Technology, 2021
A new Ground Settlement Index (GSI) to evaluate the ground movements due to tunneling is proposed. Fifteen parameters that are effective on tunneling-induced settlements are employed for the GSI introduction.

Formula for predicting ground settlement induced by tunnelling based on Gaussian function

Tunnelling and Underground Space Technology, 2020
A formula for the variation of the maximum ground settlement with the depth above a tunnel is proposed based on data from 25 field project cases and 10 model test cases.

Diaphragm Wall Deformation and Ground Settlement Caused by Dewatering Before Excavation in Strata with Leaky Aquifers

Geotechnique, 2022
In deep excavations, pre-excavation dewatering (PED) usually causes notable diaphragm wall (D-wall) deformation and ground settlement. However, this problem has not attracted sufficient attention. This paper analysed the mechanisms and control methods of

Stress-dependent water retention of granite residual soil and its implications for ground settlement

, 2021
Granite residual soil is widely used as a subgrade material in pavement engineering. Previous studies have not investigated the influence of stress on the soil water retention curve for this type of unsaturated soil or its significance for predicting ...
