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
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
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
Behavior of Geosynthetics-Strengthened Saturated Cushion Layer in Disconnected Piled-Raft System Under Seismic Loading
Springer Science and Business Media LLC - - Trang 1-14 - 2024
Amer Jihad, Mahdi Karkush
The geosynthetic reinforcement has been widely used in earthen structures, such as in geosynthetic-reinforced pile-supported embankments and buried pipes which reduces the vertical stresses on the buried structures and consequently reduces the soil arching and soil degradation under local loading. The soil arching had been investigated previously using trapdoor tests under soil self-weight and/or ...... hiện toàn bộ
Deep Excavation Supported by Diaphragm Wall: A Case Study
Springer Science and Business Media LLC - Tập 47 Số 3 - Trang 373-383 - 2017
Jasmine Nisha, J., Muttharam, M.
Space scarcity and demand for us to build skyscrapers as well as deeper basements are increasing in the present scenario. Excavations are commonly carried out in congested areas to increase underground usable spaces. Hence a case study is made on shoring system for excavation depth of 14.2 m for an office block located in Noida. The office blocks which consist of 14 stories with 3 levels of c...... hiện toàn bộ
Seismic Behaviour of Retaining Structures, Design Issues and Requalification Techniques
Springer Science and Business Media LLC - Tập 44 - Trang 167-182 - 2014
Deepankar Choudhury, Amey D. Katdare, Sanjay K. Shukla, B. Munwar Basha, Priyanka Ghosh
The realistic estimation of seismic earth pressure is very crucial for the design of retaining structures in seismic-prone areas. Several researchers have developed analytical and numerical methods for the estimation of seismic earth pressure. Some experimental studies are also reported to clearly present the seismic behaviour of retaining structures. Pseudo-static and pseudo-dynamic methods are t...... hiện toàn bộ
