Influence of Under Sleepers Rubber Mat on Propagation of Vibrations from a Railway Track Lying on a Semi-Infinite Soft Ground
Springer Science and Business Media LLC - Tập 51 - Trang 1195-1208 - 2021
T. Beda, S. Charif D’Ouazzane, G. E. Ntamack, A. Nguessong-Nkenfack, C. A. Moubeké
The damages caused on railway track and on surrounding ground by trains motion’s vibration are since many years a worry for track engineers. In the view to mitigate those negative effects, several proposals and solutions have been implemented in the track. This paper presents significant improvement in track performance resulting from the use of Under Sleepers Rubber mat (USRm) in a ballasted rail...... hiện toàn bộ
Reclamation and Ground Improvement of Soft Marine Clay for Development of Offshore Terminal 4, JNPT, Navi Mumbai
Springer Science and Business Media LLC - Tập 51 - Trang 502-519 - 2021
Kumar Pitchumani N, Aminul Islam
A container yard of around 100 Ha area was developed as part of the fourth terminal for Jawaharlal Nehru Port Trust (JNPT) in Navi Mumbai by means of reclamation in sea over soft, compressible marine clay. Ground improvement of the subsoil was warranted in order that the finished reclamation satisfies the stringent serviceability criteria. Extensive offshore geotechnical investigation campaign com...... hiện toàn bộ
Comparative Study of Linear and Non-Linear Theories of Radial Consolidation of Lightly OC Clays
Springer Science and Business Media LLC - Tập 45 - Trang 209-216 - 2014
P. Ayub Khan, M. R. Madhav, E. Saibaba Reddy
Many clays in situ are lightly overconsolidated with overconsolidation ratio ranging between 1.0 and 4.0 due to various reasons. However, the conventional theories used for analysis of radial consolidation assume the soils to be normally consolidated. For lightly OC Clays, phase transition occurs from overconsolidated to normally consolidated state due to increase of effective stress beyond the pr...... hiện toàn bộ

Reliability-Based Slope Stability Analysis of Durgawati Earthen Dam Considering Steady and Transient State Seepage Conditions Using MARS and RVM
Springer Science and Business Media LLC - Tập 49 - Trang 650-666 - 2019
Vinay Kumar, Pijush Samui, Navneet Himanshu, Avijit Burman
In this study, reliability analysis of slope failure of Durgawati earthen embankment has been performed using two different methods specifically multivariate adaptive regression splines (MARS) and relevance vector machine (RVM). Reliability index $$(\beta )$$ is calculated using both MARS and RVM under steady-state and transient-state seepage conditions. The analyses are performed for two differen...... hiện toàn bộ
Effect of Geochemical Composition of Lateritic Soils on their Geotechnical Properties
Springer Science and Business Media LLC - Tập 52 - Trang 877-894 - 2022
Ekenedilichukwu Samuel Onwo, Chukwuebuka Emeh, Ogbonnaya Igwe
Laterites are usually considered a good subgrade and sub-base materials in roads and pavements construction within tropical and subtropical regions because of their availability and affordability. In most cases, they are assumed to have homogeneous properties because of their similarity in appearance. However, the variations in the geochemical composition of their parent rocks may have a significa...... hiện toàn bộ

Estimation of Sand Grains Crushing Rate Under Uniaxial Compression Loading
Springer Science and Business Media LLC - - Trang 1-13 - 2023
Rima Sedira, Toufik Kheffache, Abdelkader Tahakourt
Understanding and controlling of granular materials behaviour require knowledge of their characteristics and the phenomenon associated with them. Among the most complex and poorly understood phenomena for granular media is the phenomenon of grain breakage and its influence on the overall macroscopic behaviour of these media during loading, during the implementation or operation of structures. The ...... hiện toàn bộ
Seismic Liquefaction Hazard and Site Response for Design of Piles in Mumbai City
Springer Science and Business Media LLC - Tập 45 - Trang 62-78 - 2014
Deepankar Choudhury, V. S. Phanikanth, Sumedh Y. Mhaske, Reshma R. Phule, Kaustav Chatterjee
Mumbai city is the financial capital of India with the highest population density and formed by reclamation of land over time from original seven different islands. As per Indian seismic design code IS 1893-Part 1, Mumbai city is located in Zone III, hence may experience moderate intensity earthquake which may lead to liquefaction of some typical soil sites of Mumbai city. In this paper, using ava...... hiện toàn bộ
Vertical Uplift Capacity of a Group of Helical Screw Anchors in Sand
Springer Science and Business Media LLC - Tập 43 - Trang 238-250 - 2013
Satyendra Mittal, Sanjeev Mukherjee
In this paper experimental investigations on the behavior of single, double and triple helical screw anchors under the influence of vertical uplift loads are presented. The testing program was conducted on three model anchors having single, double and triple helical screws installed in sand. The experimental setup was instrumented to measure the pullout load and the upward displacement of the anch...... hiện toàn bộ
