  1. 1. A Critical Review of the Observational Method

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Johan Spross; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock mechanics; observational method; Eurocode 7; reliability analysis; dam safety; tunnelling; system reliability; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Building a sustainable structure in soil or rock that satisfies all predefined technical requirements implies choosing a rational and effective construction method. An important aspect is how the performance of the structure is verified. READ MORE

  2. 2. Toward a reliability framework for the observational method

    University dissertation from Stockholm : Kungliga Tekniska högskolan

    Author : Johan Spross; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock engineering; observational method; Eurocode 7; structural safety; reliability analysis; dam safety; Bergmekanik; observationsmetoden; Eurokod 7; sannolikhetsbaserad dimensionering; dammsäkerhet; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Constructing sustainable structures in rock that satisfy all predefined technical specifications requires rational and effective construction methods. When the geotechnical behaviour is hard to predict, the Euro­pean design code, Eurocode 7, suggests application of the observational method to verify that the performance is acceptable. READ MORE

  3. 3. Geological Characterisation and the Observational Method. Application of Value of Information Analysis

    University dissertation from Stockholm : Kungliga Tekniska högskolan

    Author : Miriam Zetterlund; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Value of Information Analysis; Rock mass characterisation; Observational Method;

    Abstract : The implementation of the new European standards for geotechnical design calls for new practice in the underground construction industry in Sweden. The standard proposes the Observational Method as an alternative method when the geotechnical behaviour is difficult to predict. READ MORE

  4. 4. Observational Uncertainties in Water-Resources Modelling in Central America Methods for Uncertainty Estimation and Model Evaluation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ida Westerberg; Uppsala universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Central America; Discharge; Flow-duration curve; Fuzzy regression; GLUE; Model evaluation; Non-stationarity; Observational uncertainty; Precipitation; Quality control; Rating curve; Regionalisation; Uncertainty estimation; Ungauged basins; Water resources; Avbördningskurva; Centralamerika; GLUE; icke-stationaritet; kvalitetskontroll; modellutvärdering; nederbörd; observationsosäkerheter; avrinningsområden utan vattenfö-ringsdata; oskarp regression; osäkerhetsuppskattning; regionalisering; varaktighetskurva; vattenföring; vattenresurser; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Hydrology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Hydrologi; Hydrology; Hydrologi;

    Abstract : Knowledge about spatial and temporal variability of hydrological processes is central for sustainable water-resources management, and such knowledge is created from observational data. Hydrologic models are necessary for prediction for time periods and areas lacking data, but are affected by observational uncertainties. READ MORE

  5. 5. Reliability-based design of rock tunnel support

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : William Bjureland; Fredrik Johansson; Stefan Larsson; Johan Spross; Lars Rosén; [2020]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock engineering; reliability-based design; Eurocode 7; observational method; tunnel engineering; Bergmekanik; sannolikhetsbaserad dimensionering; Eurokod 7; observationsmetoden; tunnelbyggnad; Soil and Rock Mechanics; Jord- och bergmekanik;

    Abstract : Since 2009, design of rock tunnels can be performed in accordance with the Eurocodes, which allows that different design methodologies are applied, such as design by calculation or design using the observational method. To account for uncertainties in design, the Eurocode states that design by calculation should primarily be performed using the partial factor method or reliability-based methods. READ MORE
