Abstract: Metro lines buried in soft soil in coastal regions will inevitably suffer long-term uneven deformation during operation. In this study, the long-term deformation characteristics of metro lines in Shanghai soft deposits are ...

Abstract: Dewatering must be conducted for shallow confined aquifers located below deep excavations. However, its effects on ground settlement remain unclear, due to the complicated seepage and stress condition of the strata. In ...

Abstract: Abstract The relationship between permeability and deformation of Shanghai clay has rarely been reported, and the influence of the variation of hydraulic conductivity with deformation on embankment deformation is not clear. ...

Abstract: Deep excavations in congested urbanized areas may have a significant impact on existing structures. Therefore, protective measures must be taken to control wall deformations and related soil movements. However, little is ...

Abstract: The safety of operational tunnels impacted by nearby deep excavations has led to growing interest in the field of practical civil engineering. Many researchers have studied the performance of shield tunnels during adjacent ...

Abstract: Deep excavations conducted close to tunnels will cause an adverse impact on tunnels, and countermeasures must be taken during the excavation to ensure the safety of the tunnels. However, the effectiveness of measures to ...

Abstract: Constructed transport facilities in soft deposits deform significantly due to long-term land subsidence. A great deal of research has been carried out to study the land subsidence–induced deformations of metro tunnels, ...

Abstract: When adjacent foundation pits are excavated concurrently, the stress and deformation of the soil and structures are affected by their interactions. This paper investigates the performance of two adjacent deep foundation ...

Abstract: Pumping artesian water is mandatory in deep excavation above a shallow confined aquifer with a high piezometric head. In this study, a comprehensive monitoring program is performed to investigate the responses of far-field ...

Abstract: AbstractThis study presents a novel semi-analytical solution for the drained expansion of cylindrical and spherical cavities with a unified hardening model for both clays and sands. The three-dimensional strength of soils ...
