RISInfluence of Relative Density of Soil on Performance of Geocell-Reinforced Sand Foundations
Publisher: American Society of Civil Engineers
Abstract: The paper brings out the influence of relative density of foundation soil on performance improvement of geocell reinforcement; through model load tests on geocell-reinforced and unreinforced sand beds. Tests were carried ...
Geogrid Reinforcement for Stiffness Improvement of Railway Track Formation Over Clay Subgrade
Publisher: ASCE
Abstract: Weak subgrade condition generally develops large settlements in ballasted tracks, leading to adverse performance. To ameliorate such problems, a commonly adopted technique is to provide a thick cushion of granular ...
Influence of Lime on Shrinkage Behavior of Soils
Publisher: American Society of Civil Engineers
Abstract: Damage due to soil shrinkage is a serious problem in many parts of the world. Lime can significantly improve the performance of soils, both in terms of increase in strength and reduced swelling. However, its efficacy in ...
Lime Stabilization of Soils: Reappraisal
Publisher: American Society of Civil Engineers
Abstract: Lime generally improves the performance of soils. However, some cases reported an adverse effect. To develop an understanding of the underlying mechanisms, a systematic study covering a wide range of plasticity and mineralogy ...
Load-Carrying Mechanism of Vertical Plate Anchors in Sand
Publisher: American Society of Civil Engineers
Abstract: An experimental study on the load-carrying mechanism of vertical plate anchors is presented and discussed. It was found that, with a shallow anchor, the rupture surface reached the ground surface, leading to a general shear ...
Performance Evaluation of Coal Mine Overburden as a Potential Subballast Material in Railways with Additional Improvement Using Geocell
Publisher: ASCE
Abstract: Overburden (OB) generated from coal mining industries are a major source of environmental pollution as well as land degradation worldwide. Recycling of such waste products through effective application in the construction ...
Pullout Behavior of Geocell-Reinforced Vertical Plate Anchors under Lateral Loading
Publisher: American Society of Civil Engineers
Abstract: Vertical plate anchors are being widely used in the construction of earth retaining structures. In the present study, experimental and numerical investigations were carried out to develop an understanding of the behavior ...
Improved Performance of Railway Ballast under Impact Loads Using Shock Mats
Publisher: American Society of Civil Engineers
Abstract: Impact loads generated because of wheel and rail defects cause accelerated ballast breakage leading to adverse performance of ballasted rail tracks. In the present study, experimental and numerical investigations have been ...
Behavior of Geosynthetic Reinforced Soil Foundation Systems Supported on Stiff Clay Subgrade
Publisher: American Society of Civil Engineers
Abstract: A series of laboratory model tests was performed to investigate the behavior of geosynthetic reinforced stiff clay foundation systems under circular loading. The footing consisted of a rigid circular steel plate with a ...
