Dams have been always considered as the important infrastructures and their critical values are counted. Hence, evaluation and avoidance of dams’ destruction have a specific importance. Seepage occurrence in dams is an inevitable phenomenon. Despite all the progress in geotechnical engineering, up to now, seepage problem is the main conflict which occurs in dams. This study tried to estimate se...

Laboratory and field tests have shown that accelerated compression of peat soils occurs in response to moderate heating and an effective overconsolidation is produced on subsequent cooling. This phenomenon has been termed thermal precompression. In this study, long-term laboratory and field tests were conducted to investigate secondary compression behavior of peat as a function of stress and te...

To Lich River (TLR) system receives wastewaters from a population of nearly two million people and 100 manufactories of five industrial zones in inner city Hanoi, Vietnam. To improve quality of TLR, the embankment was carried out in 1998 and finished in 2002, resulted in width of 20 45 m, depth of 2 4 m, and maximum water flow capacity of 30 m/s. Water and sediment quality indices based on heav...

This article presents experimental research focusing on the structural failure of central core a rockfill dam using sand-bentonite mixtures. It comprised an extensive geotechnical characterization soil materials and mixtures, including compaction strength tests, as well construction 1 m high 1.5 wide physical models. The displacements cohesive cores were recorded tailored measuring system, base...

The site for the high Quxue Dam has a narrow canyon with very steep abutments and complex geology in Sichuan Province, China. Various types of embankment concrete dams were considered an asphalt-core dam (ACED), 174 m high, was selected. asphalt core is slender impervious element some concerns have been raised about reliability safety type (ACEDs). This paper presents case study highest ever bu...

The embankment dam has the advantage that it can be built in all sub-base conditions although poor topography, but weakness is seepage, so research on seepage needed. This study uses numerical modelling with GeoStudio program: SEEP/W and SLOPE/W. data used from Tugu Dam, Trenggalek, while subbase five soil types, namely clay, silty silt, sand, sand. simulation divided into two; first condition ...

Indonesia is a country that has quite high seismic activity and prone to earthquake hazards, so the construction of embankment dams in needs pay attention stability against collapse due soil mass loads. Jlantah dam located Karanganyar, Central Java. This planned for irrigation 1493 hectares raw water 150 liters/second. study aims determine safety factor (Fs) on Dam body. The method used quantit...

some heavy clay soils of the A6 and A7 types with tar emul­ sions and cutbacks on an experimental subgrade stabilization during the summer of 1937, we found that this type of soil stabilization presents some very different problems from those of soil-aggregate stabilization. Soil-cement stabilization, as described by Mr. Myers, also presents some interesting problems. According to its claims, t...
