RISBreakage Behavior of Geotextile-Encased Recycled Aggregate Columns in Soft Soil: A Numerical Investigation
Publisher: American Society of Civil Engineers
Abstract: Abstract The breakage of recycled aggregates (RAs) can significantly affect the bearing capacity
and deformation of geotextile-encased recycled aggregate columns (ERACs). A coupled
continuum-discrete model, which considers ...
Observer Design for Singularly Perturbed Systems With Multirate Sampled and Delayed Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper considers observer design problem of singularly perturbed systems (SPSs) with multirate sampled and delayed measurements. The outputs are classified into two sets which are measured at different sampling rates ...
Design Calculation Method for Soft Foundation Treatment by Geocell Mattress and Stone Column
Publisher: American Society of Civil Engineers
Abstract: Working mechanisms of a new foundation treatment technology formed by geocell reinforced mattress and stone column were discussed. Combining with a certain engineering project, techniques of treating soft soil foundation ...
Double-Beam Model to Analyze the Performance of a Pavement Structure on Geocell-Reinforced Embankment
Publisher: American Society of Civil Engineers
Abstract: In the present study, an attempt has been made to establish and analyze a model of a composite working system combining an upper pavement structure and a geocell-reinforced embankment. In the model, the geocell-reinforced ...
Calculation of Pile-soil Stress Ratio of Rigid Pile Composite Foundation with Consideration of Upward Penetration of Piles
Publisher: American Society of Civil Engineers
Abstract: Deformation performance of rigid pile composite foundation under vertical loading was discussed, and the relationship between the pile lateral friction and the relative deformation of piles and soil was studied. By adopting ...
Multiscale Features and Triggering Mechanisms of the Warm-Sector Heavy Rainfall Accompanied by Warm Shear Along the Yangtze–Huaihe Coastal Regions
Publisher: American Meteorological Society
Experiments on Active Vibration Control of a Flexible Four-Bar Linkage Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments are performed to actively suppress vibration of a flexible four-bar linkage mechanism bonded with piezoelectric materials as sensor and actuator. The control system is built up with ...
Small-Scale Rain Nonuniformity and Its Effect on Evaluation of Nonuniform Beam-Filling Error for Spaceborne Radar Rain Measurement
Publisher: American Meteorological Society
Abstract: An observational method has been proposed to sample radar echo with high range resolutions using a ground-based meteorological radar. Utilizing this method, the rainfall echo data with a high range resolution of 125 m was ...
Performance of Geosynthetic-Reinforced and Pile-Supported Embankment with Consideration of Soil Arching
Publisher: American Society of Civil Engineers
Abstract: The phenomena of soil arching is frequently encountered in geosyntheic-reinforced and pile-supported embankments (GRPSE). This study emphasizes a complicated issue of interactions integrating the embankment soil and ...
Calculation of Settlement of Composite Foundation with Rigid Piles under Flexible Ground
Publisher: American Society of Civil Engineers
Abstract: According to the character of the interaction of the pile, soil and cushion in composite foundation by fitting the vertical relative displacement distribution function of pile-soil element and introducing an elastic-plastic ...
