1. Gyromätning i tunnelnät : Gyromätningens påverkan på kortare stomnät i tunnelmiljö
Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)Sammanfattning : Geodetic measurements with a gyro theodolite are an important technique for establishing control networks in tunnelling projects. The observations are used as a separate control point outside the main network while checking the angle of the tunnels direction as it is difficult to connect the underground network to a superior network outside the tunnel.

2. Tillämpning av säkerhetskoncept - En undersökning av uppkomst och utvecklingspotential för säkerhetskoncept inom svenskt tunnelbyggande
Master-uppsats, Lunds universitet/Riskhantering (CI)Sammanfattning : Rapid growth of metropolitan areas calls for increased efficiency of land use, and subsequently more and longer tunnels than ever before are being built. The complexity of the tunnel itself, as well as considerations of spatial planning and infrastructure calls for risk management and effective methods to accomplish tunnel safety. LÄS MER
3. VERTICAL ELLIPTICAL ACCESS-SHAFTS Geometrical optimisation through FE-modelling
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Geoteknik; Lunds universitet/Institutionen för byggvetenskaperSammanfattning : Urbanisation is causing densification of cities and more and more facilities are being placed in the underground to utilise the urban space as efficiently as possible. Access to the underground is obtained by constructing vertical access shafts. LÄS MER
4. Kvarvarande grundvattennivåförändringar efter tunnelbygget genom Hallandsås
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : .... LÄS MER
5. Grundvattenpåverkan kring järnvägstunnlar i berg
Uppsats för yrkesexamina på avancerad nivå, Institutionen för geovetenskaperSammanfattning : Rock groundwater has always caused major problems when tunnelling. Water leaking into tunnels can cause large problems, not only on the construction itself but also on the environment. A continuous water leakage can lead to a declining water supply, and geotechnical problems can occur as subsidence in the ground. LÄS MER
