Abstract: Much attention has recently been paid to investigating the internal mechanisms between the void structures of foamed concrete and its mechanical behavior. This study adopted the X-ray computed tomography (X-CT) technique ...

Abstract: Deep mixed (DM) columns are being increasingly used in regions that host thick saturated soft clays. Under such geotechnical conditions, partially penetrated DM columns are predominantly designed to improve shallow ...

Abstract: Pressure-dispersed compression anchor consists of several anchor units fitted with an end plate. Limited field tests have been conducted to investigate the performance of a pressure-dispersed compression anchor system in ...

Abstract: To understand the mechanical properties of superlarge-diameter piles in complicated geologic conditions, the authors carried out centrifuge model tests that simulated the bearing characteristics of single rock-socketed ...

Abstract: Despite the ubiquity of porous materials, their mechanical behaviors (e.g., fracture) remain only partially understood. Here, we propose a novel analytical stochastic micromechanical damage model to describe the ...

Abstract: Stiffened deep-mixed columns (SDM columns) have increasingly been used to reinforce soft soils. When an embankment is constructed on a thick saturated soft clay, partially penetrated SDM columns are usually adopted. However, ...

Abstract: Soil arching exists in many earth structures, such as pile-supported embankments, tunnels, buried pipes, and retaining walls. These earth structures are sometimes subjected to surface footing loading. Limited studies showed ...

Abstract: A combined ground-improvement method has recently been adopted for embankments on soft soil that involves the use of both deep mixed (DM) columns and prefabricated vertical drains (PVDs) to increase the bearing capacity ...

Abstract: The limit equilibrium method (LEM) and the finite-element method (FEM) commonly have been used in design to calculate the factors of safety (FS) against deep-seated failure of deep-mixed (DM) column-supported embankments ...

Abstract: Foamed cement paste has been used increasingly as a backfill material in geotechnical engineering applications, such as embankments, tunnels, and retaining walls. However, limited studies have focused on the influence of ...
