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

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
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
Effect of triaxial specimen size on engineering design and analysis
Springer Science and Business Media LLC - Tập 6 - Trang 1-17 - 2015
Tarek Omar, Abouzar Sadrekarimi
Triaxial tests are often used to determine the behavior and strength characteristics of soils. Specimen size can have a significant impact on the measured shear strength. Accordingly, the selected parameters affect the related geotechnical engineering analysis and design. We tested three different specimen sizes of loose Ottawa sand in triaxial compression tests. The measured shear strength and fr...... hiện toàn bộ
Phân tích dựa trên thí nghiệm và mô hình số về các cột cát nổi trong đất sét Dịch bởi AI
Springer Science and Business Media LLC - Tập 10 - Trang 1-16 - 2019
S. Naseer, M. Sarfraz Faiz, S. Iqbal, S. M. Jamil
Việc đưa các cột cát vào trong đất sét sẽ tăng cường khả năng chịu tải của đất, tăng tốc độ lún, ngăn chặn hiện tượng chảy lỏng trong các loại đất cát lỏng lẻo và cung cấp kháng cự bên chống lại sự chuyển động ngang. Nghiên cứu này nhằm điều tra tác động của các cột nổi trong đất sét có trầm tích bùn thông qua việc phát triển các mô hình thí nghiệm quy mô nhỏ trong phòng thí nghiệm. Tác động của c...... hiện toàn bộ

Analysis of the passive earth pressure on a gravity-type anchorage for a suspension bridge
Springer Science and Business Media LLC - Tập 11 - Trang 1-7 - 2020
Hyunsung Lim, Seunghwan Seo, Sungjune Lee, Moonkyung Chung
In this study, numerical analyses have been performed for a reasonable gravity-type anchorage design. The emphasis is on evaluating the effect of the passive earth pressure for gravity-type anchorages under pullout loading. Three-dimensional FE analyses were performed for different types of bedrock and embedded depths. Based on this study, it is found that the displacement of the gravity-type anch...... hiện toàn bộ
Microstructural interpretation of effective stress equations for unsaturated sands
Springer Science and Business Media LLC - - 2023
B. J. Shwan
It was fairly accepted to interpret soil behaviour at the microstructural level by utilising the effective degree of saturation instead of the total degree of saturation in the effective stress equation for unsaturated fine-grained soils. However, this interpretation for pure sands was under-represented in the literature. On the basis of shear strength evolution with suction, this paper reports a ...... hiện toàn bộ
Evaluation of hydraulic conductivity of subsoil using electrical resistivity and ground penetrating radar data: example from Southwestern Nigeria
Springer Science and Business Media LLC - Tập 7 - Trang 1-26 - 2016
A. O. Salako, A. A. Adepelumi
Groundwater seepage has being linked to the cause of building failures in Erinle area, Ede metropolis, SW Nigeria. A comparative study of the hydraulic conductivity (K) of first two subsoil or subsurface layers underlying the area of investigation was carried out using data acquired from ground penetrating radar (GPR) and electrical resistivity (ER) surveys. Ground penetrating radar (GPR) and elec...... hiện toàn bộ
