State-of-the-Art Review on the Influence of Mica Toward Geotechnical Performance of Micaceous Sand: A Micro- to Macroscopic Perspective
Springer Science and Business Media LLC - - 2024
The presence of mica adversely alters the mechanical behavior of soil. The elastic and rebound behavior of mica particles allows their thin flakes to deform under load and recover after load removal. The resilient response of mica particles and their platy morphology substantially deteriorates the geotechnical behavior of micaceous sand due to lack of inherent cohesion while its negative influence...... hiện toàn bộ
Ultrasonic Removal of Clogging and Evaluation of Flow Capacity of Geotextile Drain
Springer Science and Business Media LLC - Tập 51 - Trang 539-551 - 2021
Clogging of geotextile drains is very common when used in fine-grained soil geo-structure such as reinforced earth retaining wall, slopes, embankments. As on date the index properties of the embedded drains are usually standardized with respect to factory-defined parameters. This paper explains the application of ultrasonic excitation for the removal of clogging of geotextiles drains extracted fro...... hiện toàn bộ
Shear Strength of Organic Clay in Kolkata Region
Springer Science and Business Media LLC - Tập 45 - Trang 25-34 - 2014
Organic clay is invariably found in the upper reaches of the soil layers in Kolkata region. To understand the strength characteristics of organic clay and also the various factors affecting its strength characteristics, consolidated undrained triaxial tests were conducted on organic clay with organic content 0, 7, 15, 20 and 26 % consolidated at effective consolidation stress (p′0) 50, 100, 150 an...... hiện toàn bộ
Use of Cement Kiln Dust for Improving the Geotechnical Properties of Collapsible Soils
Springer Science and Business Media LLC - Tập 52 - Trang 70-85 - 2021
The collapsible soils with severe collapsing problems cover many areas of new urbanized cities in Egypt. They are considered as one of the most challenge problems in geotechnical engineering, where they create major damages in most of engineering structures and infrastructures due to many bad human activities that cause infiltration of water through the foundation collapsible sand layers associate...... hiện toàn bộ
Performance Behavior of Geogrids at Interface of Ballast and Granular Soil
Springer Science and Business Media LLC - Tập 50 - Trang 753-765 - 2020
The use of geosynthetics in civil engineering projects is very common these days. The role of geogrids in stress distribution and reducing displacement is undebatable, and most of the civil engineering projects have been benefitted by the use of such products. The construction of railway embankments for heavy axle loads and high speeds is a big challenge with increasing population and demand for b...... hiện toàn bộ
Experimental Study on Uniaxial Mechanical Properties of Granite Under Thermo-liquid Coupling
Springer Science and Business Media LLC - Tập 50 Số 6 - Trang 935-947 - 2020
In order to study the uniaxial mechanical properties and failure modes of granite under the condition of thermo-liquid coupling, the granite was subjected to thermo-liquid coupling cyclic treatment at different temperatures, and then its mechanical properties were analyzed by uniaxial compression test. The results reflect the following trends: (1) the stress–strain curve generally undergoes four s...... hiện toàn bộ
Performance Improvement of Railway Ballast Using Geocells
Springer Science and Business Media LLC - Tập 42 - Trang 186-193 - 2012
Among several problems, the railway track is subjected to; spread out of ballast is a major concern, particularly in case of high speed tracks. It has been reported that geosynthetics induce additional confinement onto the ballast and thereby reducing the vertical and lateral deformation of the track substructure. Geocell being three dimensional in geometry is expected to provide better performanc...... hiện toàn bộ
Effects of Geogrid on Dynamic Strength Characteristics of Solani Sand
Springer Science and Business Media LLC - Tập 42 - Trang 287-293 - 2012
In this paper, the deformation behavior of Solani river sand and the effects of geogrid reinforcement under cyclic loads are investigated. The effects of dynamic loading parameters on Solani sand were determined in dry and saturated condition. The effects of geogrid on properties of sand were analyzed. Samples were prepared in a shake table having test bin of dimension 1.05 m × 0.6 m × 0.6 m. The ...... hiện toàn bộ
Insights into Effects of Seepage on Failure of Breakwater Mound: Experimental and Numerical Investigations
Springer Science and Business Media LLC - Tập 49 - Trang 531-542 - 2019
Identifying the collapse mechanism of a breakwater mound caused by overtopping and seepage during extreme natural disasters is an essential element of a hazard mitigation policy. This research study conducts a set of experiments to quantify the effects of seepage and overtopping on the scouring of a breakwater. A scaled model of the Kamaishi breakwater in Japan, which was significantly damaged by ...... hiện toàn bộ
