Prediction Of Slope Stability Using Artificial Neural Network (Case Study: Noabad, Mazandaran, Iran), Farzad Farrokhzad, Asskar Janalizadeh, Amin Barari
Prediction Of Slope Stability Using Artificial Neural Network (Case Study: Noabad, Mazandaran, Iran), Farzad Farrokhzad, Asskar Janalizadeh, Amin Barari
International Conference on Case Histories in Geotechnical Engineering
The surface of the earth is very rarely flat and so there are slopes nearly everywhere. The loads on slope are due to the self-weight of the soil and to external loads, which may come from foundation at the top and seismic loads. Geotechnical engineers have to pay particular attention to geology, ground water and shear strength of soils in assessing slop stability. Neural networks are very sophisticated modeling techniques, capable of modeling extremely complex functions. In particular, neural networks are non-linear. With respect to the above advantages, in this paper, artificial neural networks are developed to predict slope stability …

Influence Of Kinematic Interaction Effects On Earthquake Structure Response: Analysis Of These Effects In The Colombia Earthquake Of November 15, 2004, Gloria Estrada
International Conference on Case Histories in Geotechnical Engineering
Many authors have considered the kinematic interaction effects as favorable for seismic response of structures. However, this assumption is not always correct, because for some combinations of soil dynamic properties, foundation geometry and structural configuration, the kinematic interaction effects can lead to unfavorable performance of structures during earthquake. Therefore, the kinematic interaction effects increase or decrease the effective excitation that acts on the foundation base, in terms of their translation and rotation components. In this paper the role of kinematic interaction effects is analyzed for plate foundation embedded in different layered soil profiles, using recorded motions and several foundation geometries. …
Stress-Strain Analysis Of Different Concrete Cut Off Wall Connection Systems Case Study: Karkheh Storage Dam, Zakaria Zoorasna, Amir Hamidi, Ali Ghanbari
Stress-Strain Analysis Of Different Concrete Cut Off Wall Connection Systems Case Study: Karkheh Storage Dam, Zakaria Zoorasna, Amir Hamidi, Ali Ghanbari
International Conference on Case Histories in Geotechnical Engineering
The concrete cut off wall is usually used to control the seepage through the foundation of earth dams. It is usually made of plastic concrete. It can be connected to the core of the earth dam using different connection systems. The difference between cut off wall and core material results stress concentration in the connection zone. In fact the main cause is the large difference between stiffness of the cut off wall concrete and clayey core of the dam. This makes the stress-strain behavior complex in the connection zone. In the present study, six different details for the connection system …

Predicting Hydraulic Fracturing In Hyttejuvet Dam, S. Mohsen Haeri, Danial Faghihi
Predicting Hydraulic Fracturing In Hyttejuvet Dam, S. Mohsen Haeri, Danial Faghihi
International Conference on Case Histories in Geotechnical Engineering
Hydraulic fracturing can occur in the clay core of earth and rockfill dams if the vertical effective stress in the core is reduced to the levels that are small enough to allow a tensile fracture to occur due to hydraulic pressure of the seeping water. This situation may arise if the total stress in the core is reduced by the “arching effect” where the core settles relative to the filter or rock-fill shell of the dam. Water pressure increase in the core which occurs on first impounding of water, may reduce effective stresses further, and if they reach low enough …
Reinforcement Of Slopes For Seismic Stability, Sanjeev Malhotra, Thomas S. Lee
Reinforcement Of Slopes For Seismic Stability, Sanjeev Malhotra, Thomas S. Lee
International Conference on Case Histories in Geotechnical Engineering
According to current practice, analyzing the stability of an earth slope under seismic conditions involves applying a pseudo-static seismic load in a conventional limit equilibrium analysis or performing a displacement analysis based on the analogy of a rigid block on an inclined plane. This paper reviews the development of currently used approaches of seismic slope stability analyses, available remediation methods, and design considerations. It examines the issues of shear strength degradation, strain incompatibility, and presents three case histories of projects located in areas of high seismicity where some form of reinforcement was used to obtain seismic slope stability.

Seismic Site Effects In The Faulted Piancastagnaio Area (Italy): An Explanation Attempt, M. I. Rainone, P. Torrese, P. Signanini
International Conference on Case Histories in Geotechnical Engineering
Analysis of seismic site effects is still an open issue within projects that deal with the reduction of seismic risk. In the absence of surface and borehole arrays measurements, the main methodological approach consists of the individuation and the consequent appraisal of the surface effects in presence of “an expected” earthquake, through integrated geological, geomorphological, geological-technical, geophysical multidisciplinary surveys and by the use of numerical modelling. In historically densely populated urban areas, it is possible to verify if the calculated accelerations can be, at least qualitatively, correlated to the level of damage to buildings. However, there are frequent cases in …

Case Study Of Annoying Vibrations Generated By Unbalanced Forces Of An Offset Printing Press, Ion Vlad, Mirela - Nausica Vlad
International Conference on Case Histories in Geotechnical Engineering
In the design of machine foundations or other dynamically loaded foundations, successive corrections are used to reach the final physical system. The end product of the design procedure is the determination of a foundation – soil system which satisfactorily supports equipment or machinery. A special situation is that when the manufacturers of the machinery don’t recognize, or are unwilling to acknowledge, the unbalanced forces which are produced by their machine. Another situation, directly related to the above mentioned one, consists of the acquisition of second – hand equipment. This is the situation which has been often encountered in Romania in …
Destructive Water-Borne Pressure Waves, Gregory L. Hempen
Destructive Water-Borne Pressure Waves, Gregory L. Hempen
International Conference on Case Histories in Geotechnical Engineering
Many energetic sources (blasting, pile-driving, seismic exploration, …) near or within a water body may produce destructive, water-borne pressure waves. Pressure waves of sufficient amplitude can impact water-side structures and aquatic fauna. Such energetic sources produce pressure waves and cavitation that can cause concrete to spall, deform metal sheets that are near to the source, kill aquatic organisms, and/or damage hearing of marine mammals at large distances. Any program (energetic systems) that causes pressure waves within the water layer may be conducted in a manner that reduces the pressure waves’ severity. The methodology to reduce pressure waves does not need …
