    Sammanfattning : Water ingress into rock tunnels is a problematic phenomenon – especially in urban areas – as a lowered groundwater table may cause harmful settlements. Furthermore, too much ingress can be an incentive for the environmental court to halt the tunnel process, in order to protect the nature as part of a national interest. LÄS MER

  5. 5. Jet grouting as a method for sealing sheet pile excavations in Swedish conditions : A probabilistic approach

    Master-uppsats, KTH/Jord- och bergmekanik; KTH/Jord- och bergmekanik

    Författare :Mårten Brinck; Karl Stigenius; [2019]
    Nyckelord :Jet-grouting; probabilistic model; water; Monte-Carlo; holes;

    Sammanfattning : Jet grouting is a groundimprovement method that creates cemented columns in the soil. The soil isinjected with different pressurized fluids, through the monitor, to replace andcement the soil, often with water cement grout. There are three different commonsystems for ejecting the fluids, the single, double and triple fluid system. LÄS MER
