RISEstimating Static and Dynamic Stresses in Geosynthetic-Reinforced Pile-Supported Track-Bed under Train Moving Loads
Publisher: American Society of Civil Engineers
Abstract: This study presents an estimating method to calculate the static and the dynamic stresses in the geosynthetic-reinforced pile-supported track-bed (embankment), based on a series of full-scale model tests under train moving ...
Field Experiments on Cyclic Behaviors of Axially Loaded Piles Jacked in Soft Clay
Publisher: ASCE
Abstract: Pipe piles are increasingly used to support embankments of high-speed railways. This study presents a series of static and cyclic axial loading tests on two industrial prestressed-concrete pipe piles installed on a field ...
Analytical and Semi-Analytical Solutions for Describing Tunneling-Induced Transverse and Longitudinal Settlement Troughs
Publisher: ASCE
Abstract: It is an ongoing problem to develop a solution to predict ground deformation induced by shallow tunnels construction in dry soils. This study proposes a closed-form elastic analytical solution and a plastic analytical ...
Ground Response to Horizontal Spoil Discharge Jet Grouting with Impacts on the Existing Tunnels
Publisher: ASCE
Abstract: This study presents an application of horizontal spoil discharge jet-grouting (SDJG) columns in soil improvement between the new undercrossing tunnels and the existing tunnels in Changsha, China. To investigate the impact ...
Centrifuge Modeling of Ground and Tunnel Responses to Nearby Excavation in Soft Clay
Publisher: ASCE
Abstract: Excavations near an existing tunnel are frequently encountered in underground construction. The excavation–soil–tunnel interaction mechanism is not yet fully understood, notably the long-term behavior. This study carried ...
New Model for Predicting Permanent Strain of Granular Materials in Embankment Subjected to Low Cyclic Loadings
Publisher: ASCE
Abstract: Estimating the permanent strain of granular materials in embankments subjected to cyclic loading is a major challenge for transport engineering projects. In practice, the development of permanent strain can be divided into ...
Effect of Particle Shape on Soil Arching in the Pile-Supported Embankment by 3D Discrete-Element Method Simulation
Publisher: ASCE
Abstract: The particle shape plays an important role in controlling the behavior of granular material, thus needing to be considered in the formation and evolution of soil arching in the pile-supported embankment. Based on the ...
Mechanical Responses of Underlying Tunnels Subjected to Surface Surcharge in Soft Ground
Publisher: ASCE
Abstract: A case history of surcharge-induced large deformations and noticeable leakages occurring on existing underlying twin tunnels in soft ground is presented in this paper. The field conditions are well-documented in terms of ...
Soil Arching Effect Associated with Ground Movement and Stress Transfer Adjacent to Braced Excavation in Clayey Ground
Publisher: ASCE
Abstract: A field test for investigating the soil arching effect behind the diaphragm wall was carried out in an average 17-meter-deep, braced excavation in the normally-consolidated clayey ground. Horizontal and vertical ground ...
