During consolidation process of saturated cohesive soil the soil stiffness increases. Increase of the effective stress due to dissipation of excess pore pressure causes additional stiffness of soil mass. This phenomenon has a very important effect on the behavior of saturated cohesive soils during dynamic loading. In the current investigation the changes in maximum shear modulus. Gmax and dampi...

Resource planning in large-scale construction projects has been a complicated management issue requiring mechanisms to facilitate decision making for managers. In the present study, a computer-aided simulation model is developed based on concurrent control of resources and revenue/expenditure. The proposed method responds to the demand of resource management and scheduling in shell material emb...

The behavior of earth dams has particular complexities against dynamic forces and its assessment requiresdetailed and scientific analysis. The Farrokhi earth dam is a heterogeneous type with vertical clay core, built 150 km away from Birjand and 41 km away from Qaen on the Farrokhi River. There are concernsregarding the stability of this dam in the event of a future severe earthquake especially...

Abstract Deformation monitoring is a common practice in most of dams to ensure their structural health and safety status. Systematic frequently carried out by means geotechnical sensors geodetic techniques that, although very precise an accurate, can be time-consuming economically costly. Remote sensing are proved effective assessing deformation. Changes the structure, shell or associated infra...

Two-dimensional nonlinear dynamic analyses (NDAs) are performed for a series of hypothetical embankment dams on spatially variable liquefiable foundation layer to evaluate the utility representing with random fields conditioned different levels site characterization information. A set two-dimensional parent models (PMs), each true condition, were generated using unconditional equivalent clean s...

Abstract The study explores the factors affecting sedimentation trends in surrounding catchment area of Tarbela Dam for period 1980–2017, specifically rain and temperature. Furthermore, this also investigates seasonal effects sediment loads coming into reservoir from 2007 to 2012. statistical techniques were applied estimation climate (rainfall temperature) on inflow its area. results revealed ...
