An optimization procedure for the soil behavior identification using pressuremeter results
Springer Science and Business Media LLC - - 2021
Younes Abed
The soil parameters identification procedure is usually a trade-off between sophisticated soil model behaviour and the large number of parameters to identify. Such procedure that can accomplish both of these objectives is highly desirable, but also difficult. This paper presents a methodology for identifying soil parameters that takes into account different constitutive equations. For identifying ... hiện toàn bộ
Seepage investigations of heterogeneous soils beneath some buildings using geophysical approaches: example from southwestern Nigeria
Springer Science and Business Media LLC - Tập 10 - Trang 1-20 - 2019
Adebayo Olayinka Salako, Abayomi Gaius Osotuyi, Adekunle Abraham Adepelumi
Buildings along the flood plain of River Osun, southwest Nigeria, are usually thought of as been a safe haven for residence over the years. But in recent times with vast (increasing) population and growing urbanization, some of the buildings currently experience structural damages not related to constructional designs but rather ground conditions around building foundations. The ground conditions ... hiện toàn bộ
Strength characteristics of genetically different rice and coconut husk ash compacted shales
Springer Science and Business Media LLC - Tập 6 - Trang 1-14 - 2015
Ibrahim Adewuyi Oyediran, Oluwafemi Festus Fadamoro
The strength characteristics of two genetically different shales treated with both Rice Husk Ash (RHA) and Coconut Husk Ash (CHA) was evaluated to elucidate responses and effects, examine effectiveness of the additives with a view to ultimately provide economically viable and environmental friendly options for modification and hence stabilization. 2 to 20 % by weight of both RHA and CHA were separ... hiện toàn bộ
Evaluation of adding crushed glass to different combinations of cement-stabilized sand
Springer Science and Business Media LLC - Tập 8 - Trang 1-12 - 2017
Sina Salamatpoor, Siavash Salamatpoor
One of the methods that can stabilize clean sand type (SP) is blending the waste crushed glass and cement with these sands. In this paper, the laboratory tests are conducted on combination of clean sand, crushed glass, and cement in different condition for soil stabilization. Blends were stabilized by cement with 3, 5 and 10 weight percent of specimens. Different compounds of crushed glass used in... hiện toàn bộ
Effect of nonplastic silt content on undrained shear strength of sand–silt mixtures

Monitoring and evaluating of slope stability for setting out of critical limit at slope stability radar
Springer Science and Business Media LLC - Tập 8 - Trang 1-16 - 2017
Ajay Kumar, Ritika Rathee
Slope stability monitoring and evaluating play vital role in the risk management of open cast mines. Generally, Issue of slope failure occurs at open cast mines due to undisciplined mining, impacts of weather conditions. Slope stability radar provide slope stability warning impending failure and also it has used for setting out threshold value. This threshold value obtained from parameter value, s... hiện toàn bộ
Reinforcing effects of bolting in jointed rock mass
Springer Science and Business Media LLC - Tập 7 - Trang 1-9 - 2016
Hae-Sung An, Sang-Duk Lee
A rock bolt is one of 3 major support members, including shotcrete, steel rib, playing an important role in stabilizing the underground space with its various functions. Currently, studies at home and abroad tend to focus on the development of new rock bolt methods. For most of the studies on the reinforcing effects, a numerical analysis has been adopted; however the experimental analysis is insuf... hiện toàn bộ
Pre-stressed anchor cable force evolution laws of plane sliding bedding slopes
Springer Science and Business Media LLC - Tập 14 - Trang 1-15 - 2023
Victor Mwango Bowa, Eugie Kabwe
This paper aims to understand how anchor cable force evolution laws can improve reinforcement designs. The self-developed weak plane sustained deterioration technology was conducted in the indoor test on the reinforced bedding rock slope containing a linear type weak plane. The force evolution laws of anchor cables with the weak plane sustained deterioration was studied. Furthermore, the theoretic... hiện toàn bộ
Mesh-free kinematic shakedown analysis of cohesive soils
Springer Science and Business Media LLC - - 2024
Z. Nosrati, S. M. Binesh
A novel mesh-free solution is proposed for kinematic shakedown analysis of cohesive soils under repeating loads. For this purpose, the continuous velocity field in the mathematical expression of Koiter’s theorem is discretized by the Radial Point Interpolation Method (RPIM), as a mesh-free approach. The strain rate smoothing technique is implemented in conjunction with the RPIM to satisfy the admi... hiện toàn bộ
Lime treatment of a diesel-contaminated coarse-grained soil for reuse in geotechnical applications
Springer Science and Business Media LLC - Tập 11 - Trang 1-15 - 2020
Natalia de Souza Correia, Fernando Henrique Martins Portelinha, Igor Santos Mendes, Jose Wilson Batista da Silva
Potential reuse of oil-contaminated soils guidance policies are demonstrating ways to reuse these materials in engineering applications. However, the engineering properties of these materials are highly altered after contamination. Alternatively, chemical stabilization treatments can improve oil-contaminated soil properties for its reuse in geotechnical applications. This study investigates the ef... hiện toàn bộ
