اولین مسئله ای که در ساخت سدهای خاکی مدرن حیاتی می باشد کنترل و رفتارنگری صحیح این سازه های ژئوتکنیکی می باشد. از نتایج تجربی این کار تبیین ظوابطی است که بتواند ما را در انجام کارهای آینده کمک کند. در حال حاضر به نظر می رسد که روش آنالیز معکوس یک ابزار بسیار سودمند در دست مهندسین برای فهمیدن رفتار سد می باشد. با پیشرفت های حاصل شده در زمینه روش های تحلیلی و نیز وجود داده های خوب و انجام آنالیزه...

it is correct control and monitoring of modern embankment dams that are very vital in the geotechniqual constructions. the improvement of methods of stability control, using the effective stress and the measurement of ganglionic water pressure in embankment dams cause more the safety for this kind of dams. nowedays there is such an idea that in stead of using of being safety factor against coas...

Iran, as a leading country in the dam construction industry, is located in one of the earthquake-prone regions of the world. Dams are important sources of hydroelectric power. Failure of these structures causes catastrophic damage. Therefore, evaluating the behavior of dams under seismic loading is an important issue. The present study focuses on the prediction of the slope displacements of emb...

construction of railway embankments on loose beds without using any methods of soil improvement (e.g. stone columns in silt and clay beds, deep soil mixing method, jet grouting and also using micropiles individually or in groups form) leads to  reduction of embankment slope gradient, which significantly increases the volume of soil operation. generally, micropile as a reinforcing element with t...

Aging infrastructure in the US has gained quite a bit of attention in the past decade. Being one type of a critical infrastructure, embankment dams in the US require significant investment to upgrade the deteriorated parts. Due to limited budgets, understanding the behavior of structures over time through risk assessment is essential to prioritize dams. During the risk assessment for embankment...

in the first impounding of rockfill dams, additional settlements occur in upstream side in saturated rockfills due to collapse phenomenon even high rainy seasons can cause additional deformation in the dumped rockfills. unfortunately these displacements are not taken into account in the conventional numerical models which are currently used to predict embankment dam behavior during impounding. ...

Reducing the settlements of soft foundation effectively is a critical problem of high-speed railway construction in China. The new CFG pile-slab structure composite foundation is a ground treatment technique which is applied on CFG pile foundation and pile-slab structure composite foundation. Based on the experience of constructing Beijing-Shanghai high-speed railway in China, the settlement-co...
