  1. 1. Compaction Simulation for Prepreg-AutoclaveManufacturing : Improvements and Simplifications of Two Compaction Simulation Methodologies

    University essay from KTH/Lättkonstruktioner

    Author : Charlotte Chan; [2019]
    Keywords : ;

    Abstract : In a competitive market such as the aerospace industry, the use of manufacturing process simulation is vital to decrease time and cost of tooling and process development. In the autoclave process, to obtain an uniform part with no void, it is crucial to understand the compaction phenomenon. READ MORE

  2. 2. An alarm system for pore pressure measurements in the foundation ofconcrete dams : a case study of Storfinnforsen buttress dam

    University essay from KTH/Jord- och bergmekanik

    Author : Daniel Falcão de Queiroz; [2018]
    Keywords : Buttress dams; dam foundation; pore pressure; alarm system; alarm limits; sliding in the rock mass; uplift pressure; piezometers.; Lamelldammar; dammgrundläggning; portryck; alarm system; alarmgränser; glidning i bergmassan; upptryck; portrycksmätare;

    Abstract : Concrete buttress dams are relatively light structures and less demandingon foundations; because of that, they may have problems with upliftforces and horizontal joints in the area of the dam´s foundation maypresent a failure mode through sliding. The Storfinnforsen dam, thelargest concrete dam in Sweden, had its foundation studied recently andthe discovery of sub-horizontal joints in the bedrock led to the necessityof having the safety of the dam foundation to sliding assessed.

  3. 3. Pore water pressure and settlements generated from water driven DTH-drilling : - A field study

    University essay from KTH/Jord- och bergmekanik

    Author : Moa Asplind; [2017]
    Keywords : DTH drilling; hydraulic drilling; settlements; pore pressure; Venturi effect; Sänkhammarborrning; vattendriven borrning; sättningar; porvattentryck; Venturi effekten.;

    Abstract : Foundation work can cause damage to adjacent buildings and infrastructure. Drilling is performed in sensitive areas in urban projects and where the ground conditions are difficult. It is important to be aware of the installation effects from drilling. READ MORE

  4. 4. The potential use of S-HYPE in the work of predicting landslides

    University essay from KTH/Mark- och vattenteknik

    Author : Sara Edvardsson; [2017]
    Keywords : ;

    Abstract : Landslides are expensive for the community as it causes changes to for example infrastructure, changes in land used for cultivation and can also result in loss of life. Climate change will in the future introduce higher amounts of precipitation in Sweden, which increases the risks of landslides, as groundwater levels will increase. READ MORE

  5. 5. Pore pressures and settlements generated from two different pile drilling methods

    University essay from KTH/Jord- och bergmekanik

    Author : Rasmus Ahlund; Oscar Ögren; [2016]
    Keywords : DTH; bored piles; pore pressure; settlements; over-drilling; sänkhammarborrning; borrade pålar; portryck; sättningar; överborrning;

    Abstract : For piling works in sensitive soil, especially in inner city projects, it is essential to be aware of the available methods and to choose the most suitable method to minimize the risk of damaging existing buildings or endanger the workers at the construction site. Down-the-hole drilling of piles is a relatively safe method and can be separated into drilling with air powered hammers and water powered hammers. READ MORE
