Shallow landslides are induced by extreme hydrological events or by events of medium intensity but prolonged over time. Such slips involve generally limited portions of land; however, they are dangerous due to the absence of warning signals and the lack of knowledge regarding their possible evolution. The aim of this paper is to study the evolution of shallow landslides affected by snowmelt and rainfall and to compare the observations done in situ by means of a statistical analysis of meteorological variables with...

In recent decades, society has paid increased attention to issues related to observed climate change, which also includes recurring extreme hydrological phenomena. Shortterm heavy rainfall and long-term droughts draw attention to the increased need for hydraulic structures, providing protection against floods or creating water supplies in times of water scarcity. Flood control levees are an important part of flood protection measures. We should give them constant attention to prevent them from collapsing, and thei...

The California Bearing Ratio (CBR) is a test designed to measure the bearing capacity of the subgrade during a construction of roads. It has also been used as a baring capacity test for unpaved aircraft runways and other transport areas. Nowadays, CBR is used as a proof and control test in evaluating the bearing capacity of subgrade and structural layers of roads. A distinction is made between the laboratory test and the in-situ test, which is nowadays no longer widely used. This is due to several reasons. It is p...

The groundwater flow problems are often solved using numerical models. The numerical models based of known fundamental solution, known as Trefftz methods, represents one of the efficient approaches used to solve potential flow phenomena described by the Laplace differential equation. The Trefftz-like methods, such as the boundary element method (BEM), represent a very efficient approach to solving groundwater flow problems. However, the implementation of BEM is cumbersome because of the fundamental solution singul...

Many reasons deform the cavity inside the soil. The reasons can be classified to two main reasons natural and artificial reasons. Natural reasons belong to the type of soil (It is usually due to materials that enter the formation of the soil and may be affected by natural factors). And artificial reasons due to human work inside the ground like old buildings. The size of these cavities effect on the capacity on structures and it can cause huge damages for the structures. Experimental study presents the effect of s...

For the geological risk assessment of intermediate underground condition by excavation work, since rocks and geologic structure of each country is different, it is necessary to objectify or classify quantitatively intermediate underground risk evaluation in accordance with Korean geologic characteristics. It could be summarized major factors of rock failure and ground subsidence by geological and geotechnical features as overburden, ground characteristics of soil and rock, geologic structures, hydrogeology, high s...

Following the increased use of sealing structures built in order to isolate historically polluted sites or to repair infiltrations inflicted to the levee of dams, it emerged the need to choose the right materials for constructing barriers using cutoff wall technique. The objective of this paper is to assess the range of suitable material combinations (water, cement and bentonite) in order to attain proper compressive strength, permeability and ductility requirements of such a structure. This paper proposes the rep...

Research Object and Relevance. Inclinometer measurements occupy an important place in geotechnical monitoring of hydraulic structures. Borehole inclinometers are used on tailings dams - they allow you to determine horizontal displacements, shifts, curvature of the casing pipe throughout its entire depth. An important part of the processing of initial data is the identification of various systematic errors. The authors of the article faced the problem of interpreting the displacements at the tailings dam of The Erd...

Infostructures element increased in demand last forty years, these elements provide increasing in the resistance of structures and service age. Due to the difficulty of studying the behavior of parts that embedded in soil special for the anchor plate. A numerical study was adopted to study the behavior of anchor plate inside the soil to see the deformations and the stress that deform inside the soil, also the reaction of soil companion under the effect of this loads. Abaqus is a complete program used to solve the ...

Wastewater treatment and desalination are considered important solutions to meet the water scarcity in Jordan. The irrigation with reclaimed wastewater, that usually has elevated salinity levels, may adversely change soil structure, stability, and hydraulic properties. Water traditional desalination techniques require huge energy and capital investments. Zeolites in normal and nano scales enhance the desalination process performance and reduce its economic and energy requirements. In this study, batch experiments ...

This paper experimentally investigated the effect of using nanomaterials to improve soft soils. Laboratory experimental tests were carried out on loessial soils collected from two different sites in Romania. Two different types of nanomaterials were used in this research, which is namely Nano-MgO with different percentages (0.5%, 0.75%, 1%, and 2%), and Nano-Al2O3 with percentages (0.5%,1%, and 2%), were added to the soil samples, to study their effect on the strength, consistency limits and compressibility of the...

When studying the mechanical behavior of hydrated binders, it is necessary to prevent hydration contraction tensile failure in order to properly characterize the mechanical properties of the material. This is regulated by standards for cement testing, however for the case of water-cement-bentonite mixtures the influence of standard sand is not thoroughly studied. Since the hydration shrinkage and water suction is different for cement and bentonite, a range of eleven combinations of water-cement-bentonite were used...
