One of the main concerns to design earth dam is the stability of the upstream slope of the earth dam in phase of rapid drawdown. Confined pore water pressure reduces the effective stress in this mode, so possibility of the instability and slippage will be increased. The main goal of this research is to investigate changes in the pore water pressure by using horizontal drains in upstream slope o...

Various earth-retaining structures are extensively used in different civil engineering projects. Using the results of experimental and numerical modeling, effect earthquake loading on distribution earth lateral pressures basement walls was investigated. The UBCHYST constitutive model performed simulations, using 12 centrifuge dynamic tests, a calibration process conducted to obtain proper input...

Abstract: The design of retaining walls requires the complete knowledge of the earth pressure distribution behind the wall. Due to the complex soil-structure effect, the estimation of earth pressure is not an easy task; even in the static case. The problem becomes even more complex for the dynamic (i.e., seismic) analysis and design of retaining walls. Several earth pressure models have been de...
