Analysis and prediction of brittle failure in rock blocks having a circular tunnel under uniaxial compression using acoustic Emission technique: laboratory testing and numerical simulationAbstract In this research, the failure mechanism and anomalous behavior of intact and jointed rock block having a circular tunnel under compression are studied. This was done by monitoring the progressive failure of a rock tunnel subjected to uniaxial loading. The tests were conducted in sandstone blocks and “Acoustic Emission ” (AE) techni... ... hiện toàn bộ

Hydro-engineering solution for a sustainable groundwater management at a cross border region: case of Lake Nyasa/Malawi basin, Tanzania
Springer Science and Business Media LLC - Tập 7 - Trang 1-20 - 2016
A groundwater resources assessment has been carried out for the Lake Nyasa Basin east Africa, with reference to sub catchments further to the whole basin wise analysis, including quantification of potential yields from the aquifers. Numerical groundwater models, MODFLOW-SURFACT coupled with Visual MODFLOW, were used to assess sub-basin groundwater sustainability (Via “Zone Budget” software package...... hiện toàn bộ
Characterization of expansive soils treated with lignosulfonate
Springer Science and Business Media LLC - Tập 11 - Trang 1-10 - 2020
The current study examines the potential of lignosulfonate to enhance the engineering behavior of two locally available expansive soils. The expansive soils were collected from Vijayawada and Amaravathi, located in the Capital Region of Andhra Pradesh, India. The soils were treated with four different percentages (0.5, 1, 2, and 4) of lignosulfonate and were allowed to interact for 7 and 28 days. ...... hiện toàn bộ
Model tests on ordinary and geosynthetic encased stone columns with recycled aggregates as filler material
Springer Science and Business Media LLC - Tập 15 - Trang 1-13 - 2024
Sincethe availability of natural aggregates is very sparse, recycled industrial and construction waste provides a sustainable alternative to ground improvement using vibro replacement method. Utilizing recycled building waste caters the requirement for its disposal and offers an effective remedy for the scarcity of natural resources. The aim of this study was to give a sustainable alternative for ...... hiện toàn bộ
Influences of variations in the sledgehammer trajectory and collinearity of the geophone array in an MASW survey on the shear-wave velocity profile
Springer Science and Business Media LLC - Tập 11 - Trang 1-12 - 2020
In professional activities aimed at seismic site classification, geophysical methods based on measurements of surface waves are often used to measure the shear-wave velocity (Vs), with the MASW survey being one of the most common techniques employed for this purpose. An MASW survey is characterized by an in-field configuration that requires a relatively simple setup; however, several uncertainties...... hiện toàn bộ
Reinforcing effects of bolting in jointed rock mass
Springer Science and Business Media LLC - Tập 7 - Trang 1-9 - 2016
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
Evaluation of adding crushed glass to different combinations of cement-stabilized sand
Springer Science and Business Media LLC - Tập 8 - Trang 1-12 - 2017
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

Loading rate conditions and specimen size effect on strength and deformability of rock materials under uniaxial compression
Springer Science and Business Media LLC - Tập 9 - Trang 1-11 - 2018
In this study, various rock and cementitious rock-like material specimens with same ratio of length to diameter and different sizes were tested under various deformation controlled loading rate (mm/min) and load controlled rate (kN/s) conditions. According to the results obtained from 93 specimens of 5 different types of rock material and 2 different rock-like materials (cement paste and a concret...... hiện toàn bộ
