  1. 1. A Critical Review of the Observational Method

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Johan Spross; Stefan Larsson; Fredrik Johansson; Joakim Jeppsson; Lars Rosén; [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; Stefan Larsson; Fredrik Johansson; Rasmus Müller; John Harrison; [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. On reliability-based design of rock tunnel support

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : William Bjureland; Stefan Larsson; Fredrik Johansson; Johan Spross; Lars Rosén; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock engineering; reliability-based design; Eurocode 7; observational method; tunnel engineering; Bergmekanik; sannolikhetsbaserad dimensionering; Eurokod 7; observationsmetoden; tunnelbyggnation.; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Tunneling involves large uncertainties. Since 2009, design of rock tunnels in European countries should be performed in accordance with the Eurocodes. The main principle in the Eurocodes is that it must be shown in all design situations that no relevant limit state is exceeded. READ MORE

  4. 4. 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

  5. 5. Managing uncertainties in geotechnical parameters From the perspective of Eurocode 7

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Anders Prästings; Stefan Larsson; Johan Spross; Rasmus Müller; Kok-Kwang Phoon; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eurocode 7; Characteristic value; Partial-factor method; Reliability-based design; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Geotechnical engineering is strongly associated with large uncertainties. Geotechnical site investigations are made only at discrete points and most of a soil volume is never tested. A major issue is therefore how to cost effectively reduce geotechnical uncertainties with respect to structural performance. READ MORE
