RISDynamic Properties of Cement-Treated Marine Clay
Publisher: ASCE
Abstract: Deep cement mixing and jet grouting is a widely adopted ground improvement method to solidify soft sediments. Several reports are available on the static strength and maximum shear modulus of cement-treated ground. This ...
Dynamic Performance Assessment of MSE Walls under High-Speed Train Loads
Publisher: American Society of Civil Engineers
Abstract: Mechanically stabilized earth (MSE) retaining walls have been successfully implemented in numerous applications, particularly where dynamic loads such as earthquake and traffic loading are prevalent. However, using MSE ...
Assessment of a Hyperbolic Model for Undrained-Cyclic Shearing of Remolded Clay
Publisher: ASCE
Abstract: The behavior of remolded kaolin clay is examined using cyclic triaxial and resonant column tests. The damping of kaolin is shown to be largely hysteretic, and its cyclic degradation behavior is affected predominantly by ...
Effects of Tunneling-Induced Ground Movements on Stability of Piled Raft Foundation: Three-Dimensional Finite-Element Approach
Publisher: ASCE
Abstract: Across the globe, rapid urbanization demands the construction of tunnels within the vicinity of high-rise buildings supported on piled raft foundations. As a consequence, ground movements caused by such tunneling works ...
Static and Large-Strain Dynamic Properties of Sand–Rubber Tire Shred Mixtures
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of experimental investigations on sand–rubber tire shred mixtures. The sand and rubber tire shreds considered were of uniform fine size (<2 mm). Static and dynamic characterization was ...
Shear Modulus and Damping Ratio Model for Cement Treated Clay
Publisher: American Society of Civil Engineers
Abstract: A hyperbolic model-based normalized shear modulus reduction (G/Gmax) formulation for cement treated clay is presented. This three-parameter normalized shear modulus reduction model can be constructed using maximum shear ...
Performance of Geo-Base Isolation System with Geogrid Reinforcement
Publisher: American Society of Civil Engineers
Abstract: To mitigate earthquake-related damage to buildings, a simple alternative method to conventional base isolation techniques is to provide a geo-base isolation (GBI) system, composed of a scrap tire–sand mixture, between the ...
Three-Dimensional Simulation of Seismic Slope–Foundation–Structure Interaction for Buildings Near Shallow Slopes
Publisher: ASCE
Abstract: Buildings constructed adjacent to the slope crest in seismically active areas might be exposed to serious danger when they are subjected to strong earthquake excitations. The ground conditions can influence the seismic ...
Numerical Study of Liquefaction-Induced Uplift of Underground Structure
Publisher: ASCE
Abstract: A finite-difference modeling was performed to investigate the liquefaction-induced uplift of an underground structure. The liquefaction-induced uplift of a 5 m diameter underground structure buried at a depth of ...
Investigation of Geotechnical Seismic Isolation Bed in Horizontal Vibration Mitigation
Publisher: ASCE
Abstract: Recently, a ground-borne vibration mitigation solution using rigid wave impeding blocks embedded in the foundation bed of buildings/embankments has emerged as a passive vibration isolation mechanism, wherein energy dissipation ...
