  1. 1. Seepage monitoring in embankment dams

    Författare :Sam Johansson; KTH; []
    Nyckelord :;

    Sammanfattning : Internal erosion, which is one of the major reasons forembankment dam failure, causes an increased seepage flow due toloss of fines. A seepage measuring system is therefore a vitalpart of an embankment dam’s monitoring system. Manyexisting seepage monitoring systems are not however sensitiveenough to detect small changes in the seepage flow. LÄS MER

  3. 2. Internal erosion in embankment dams : fluid flow through and deformation of porous media

    Författare :J. Gunnar I. Hellström; Thanasis D. Papathanasiou; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : A basic understanding of fluid flow through a porous media facilitates a comprehensive understanding of internal erosion in embankment dams. Hence, it is necessary to reveal the detailed seepage flow, the flow-induced forces acting within the porous media and the fluid flow deformation of the porous media. LÄS MER

  4. 3. Beyond the deterministic approach - on the feasibility of data assimilation methods in geotechnics

    Författare :Amardeep Amavasai; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Embankment; Uncertainty analysis; Data Assimilation; soft soils;

    Sammanfattning : The surge in economic and social development has resulted in significant challenges, especially for linear physical infrastructure. A substantial part of the ageing physical linear infrastructure has been built on problematic soils and often have poorly documented foundation solutions. LÄS MER

  5. 4. Train-Induced Vibrations on Embankments and in Buildings : Prediction and Validation of Some Models

    Författare :Christoffer With; Anders Bodare; Sigurdur Erlingsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building; embankment; environment; flexibility; model; phase; Building engineering; Byggnadsteknik;

  7. 5. Resistivity investigation and monitoring for detection of internal erosion and anomalous seepage in embankment dams

    Författare :Pontus Sjödahl; Teknisk geologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogeologi; teknisk geologi; internal erosion; Hydrogeology; geographical and geological engineering; time-lapse inversion; inversion; monitoring; modelling; resistivity; detection; leakage; seepage; teknisk geografi; embankment dam;

    Sammanfattning : Methods for monitoring seepage and detecting internal erosion are essential for the safety evaluation of embankment dams. Internal erosion is one of the major reasons for embankment dam failures, and there are several tenths of thousands of large embankment dams in the world. LÄS MER
