Abstract [en]

Underground constructions in urban areas often lead to environmental impact such as decline of the groundwater levels, which in turn may give subsidence of ground, decay of foundations and sometimes impact on vegetation. Measuring of groundwater levels is an important part of the monitoring programmes at major soil and rock construction projects in urban areas. The aim of the research project has been to define the required measurement period before the start of the construction project and to define the impact on the groundwater levels using non-equivalent measurements from monitoring programmes in an urban area. In this paper various statistical methods, such as a modified double mass method and a stepwise regression method, are used for the analyses of the groundwater levels. The project was carried out in relation to the major ring road construction project in the Stockholm area (Norra Länken). The research project shows that observation tubes within urban areas often have a strongly complex fluctuation pattern of groundwater levels, which requires several years of pre-construction measurements in order to be useable in a monitoring programme. Tubes in more natural terrains, parks etc, usually require a measurement period of 15-18 month, using monthly measurements. The methods used also rely on a careful selection of reference sites.
