  1. 1. Risk Estimation of Groundwater Drawdown in Subsidence Sensitive Areas

    Författare :Jonas Sundell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; uncertainty quantification; urban hydrogeology; pore pressure reduction; subsidence; geostatistics; groundwater leakage; soft soil; groundwater drawdown; spatial variability; settlement; probabilistic; risk assessment;

    Sammanfattning : Groundwater drawdown induced ground subsidence is a severe problem in many regions around the world. Leakage of groundwater into a sub-surface construction, resulting in drawdown and subsequent subsidence, can lead to immense damage costs on buildings and installations in urban areas. LÄS MER

  3. 2. Risk Assessment of Groundwater Drawdown in Subsidence Sensitive Areas

    Författare :Jonas Sundell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverse modelling; cost-benefit analysis; probabilistic; groundwater drawdown; urban hydrogeology; economic valuation; groundwater leakage; subsidence; value of information analysis.; spatial variability; uncertainty quantification; risk assessment;

    Sammanfattning : Groundwater leakage into sub-surface constructions can result in drawdown, subsidence in compressible materials, and costly damage to buildings and installations. When planning for sub-surface constructions where there is a risk for land subsidence due to groundwater drawdown, the need for safety measures must be carefully evaluated and managed. LÄS MER

  4. 3. Hydrogeological Methods in Geotechnical Engineering: Applied to settlements caused by underground construction

    Författare :Jenny Persson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; excavation; tunnel; hydrogeology; consolidation; pumping test; Groundwater; inflow rate; settlement; transmissivity; pore pressure; clay;

    Sammanfattning : Improvement in the infrastructure in urban areas generally involves underground construction with tunneling and deep excavations. One important consideration when constructing in cities founded on soft soil is settlement resulting from groundwater drawdown. The potential cost of excessive settlement in these projects is immense. LÄS MER

  5. 4. Managing hydrogeological risks in underground construction

    Författare :Johanna Merisalu; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; risk management; groundwater drawdown-induced damages; cost–benefit analysis; uncertainties; decision support;

    Sammanfattning : Groundwater leakage into underground constructions can cause groundwater drawdown and subsequently costly damages to objects impacted by changes in groundwater conditions. In order to reduce the damage risk, risk-reducing measures can be implemented. LÄS MER
