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
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

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
The effect of clay content on the relation between uniaxial compressive strength and needle penetration index for clay-bearing rocks
Springer Science and Business Media LLC - - 2021
S. Kahraman, A. Sercan Aloglu, Egemen Saygin, Bilal Aydin
AbstractThe needle penetration index (NPI) test is a non-destructive test that is applicable both in the field and laboratory, and does not require any special sample preparation. This test has been used for the estimation of physico-mechanical properties of soft rocks. In this study, the influence of the clay content on the relation between uniaxial compressive st...... hiện toàn bộ
Effects of the lateral stress on the inner frictional resistance of pipe piles driven into sand
Springer Science and Business Media LLC - Tập 7 - Trang 1-14 - 2016
Janaka J. Kumara, Yoshiaki Kikuchi, Takashi Kurashina
The inner frictional resistance of pipe piles depends on the degree of soil plugging. Many factors including pile diameter, lateral stress at the pile tip and geometrical conditions of piles could influence the soil plugging. In this paper, the effects of inner sleeves attached at the pile base on the inner frictional resistance are discussed, particularly highlighting the lateral stresses at the ...... hiện toàn bộ
On the development of a non-linear calibration relationship for the purpose of clay content estimation from the natural gamma ray log
Springer Science and Business Media LLC - Tập 8 - Trang 1-18 - 2017
Golnaz Jozanikohan
The Shurijeh Formation of Early Cretaceous age is an important clastic sandstone reservoir rock in the Gonbadli field, NE Iran. The quantitative determination of Shurijeh clay minerals has been considered to be a very important and challenging task due to the heterogeneity of formation. The calibrated gamma ray log has been traditionally used as the primary estimator of volume of clay in the subsu...... hiện toàn bộ
