Urbanization and development in arid and semiarid have brought increased interest in the improvement of water sensitive soils susceptible to volume change. This investigating aims to study the possibility of using fibers along cement to improve the mechanical properties of collapsible soil and hence improve cement-treated soil behavior. The testing program conducted includes compaction characterizations, collapse potential, and shear parameters. The experimental program was conducted under both ...

The mechanical behavior of low porosity carbonate rocks is investigated by a series of conventional triaxial compression tests performed at room temperature, at various confining pressures up to 70 MPa and at a constant strain rate of 5 × 10 −5 s−1. Aiming at an improvement of the accuracy and quality of the constant mi of the non-linear Hoek–Brown criterion for jointed rock, four dense, high strength and low-porosity carbonate rocks were tested in conventional triaxial testing, under confining ...

Desaturation of in-situ saturated sandy soils is emerging as a new cost effective and environment friendly liquefaction mitigation technique. In the present study, stress controlled undrained cyclic triaxial tests have been conducted on air injected-desaturated sandy soil and various important issues such as number of cycles required for initial liquefaction, cyclic strength of desaturated sand, modes of failure, evolution of pore pressure, have been explored in detail. Number of cycles required...

To avoid over-tailing and limit the risk of failure in open-pit mines, choosing an ideal and stable slope is critical. The major goal of this study was to provide a stable and optimal design for the ultimate slope of the Shadan Open Pit Mine using numerical modeling to calculate the minimum factor of safety equal to 1.20 under various situations of the slope's geometric specifications. In FLAC3D program, the finite difference method (FDM) was used according to the shear strength reduction (SSR) ...

Central composite design, a type of response surface methodology (RSM), was combined with Derringer and Suich desirability function approach (DFA) in this study to optimize multi-additives for expansive soil improvement. The additives, which ranged from 2 to 8% for Ordinary Portland cement (CM) and 0–20% for both sawdust ash (SDA) and quarry dust (QD), were all added by air-dried weight of the expansive soil. The soil properties evaluated as the responses include the unconfined compressive stren...

Rockburst seriously threaten the economic benefits and construction safety of deep tunnel. Rockburst prediction is one of the key scientific issues in rockburst research. In this paper, the elastic strain energy is regarded as the inherent power of rockburst. A multi-factor rockburst criterion is established which consider the properties of rock, the intactness of the rock mass and the releasable elastic strain energy of surrounding rock mass. Using the three-dimensional discrete element method ...

In this investigation, the failure behaviour of “H” shaped non-persistent cracks under uniaxial load has been examined using experimental tests and Particle Flow Cod (PFC). Dimensions of produced concrete sample was 18 cm × 18 cm × 5 cm. Inside the sample, one “H” shaped non-persistent joints were provided. The angles of the “H” shaped non-persistent joint were 0°, 30°, 60°, and 90° degrees. A total of 12 layouts were considered for pre-existing joints in which the larger joints were 60 cm long ...

Understanding of impact characteristics is the basis of studying the hydrodynamic characteristics of water–rock flow. The impact and vibration characteristics of water-stone flow on protective structures were comprehensively studied in the research presented in this paper using an indoor large-scale test. Five groups (A–E) of graded crushed stone particles, combined with six levels of solid–liquid ratio (0.01, 0.05, 0.10, 0.15, 0.20, and 0.25) were used in this testing program. The spectrum and ...

This paper presents a study on Chlef sand to examine the effect of fines content (Fc), relative density (RD) and initial conditions on the compressibility behavior. The interpretation of the results is based on the concept of the intergranular voids ratio (es) and two hypoplastic parameters model Hs and n for calculation of the maximum voids ratio. The œdometric tests results made in the laboratory show that the fines content transition (Fct) of Chlef sand is in good agreement with the results p...

The preliminary responses on stability assessment are very effective in discontinuous rock slope stabilisations, which geo-mechanical empirical classifications/approaches can be evaluated. Although there are several geomechanical classifications for rock mass characteristics, they still have some complexities and shortcomings. In this paper, correlations based on two flexible classification systems, namely slope mass rating (SMR) and Barton’s Qslope, has been discussed as a connection between fa...
