Description

A final report summarizing the research conducted on geotechnical site assessment methodologies relevant to Land 3/4 sites. Two areas of research have been investigated; in situ stress determination by the hydraulic fracturing method in basic volcanics and sediments and the laboratory determination of hydraulic fracture tensile strength. The analysis and interpretation of the hydraulic fracturing test data from a programme of testing in the Vale of Belvoir is discussed in detail particularly in respect of the effects of pore water pressure and fluid diffusion in the rocks being tested. The regional stress regime of the Vale of Belvoir is discussed with respect to the results of the in situ stress determination. A method for determining the hydraulic fracture tensile strength in the laboratory is described. The results of a series of laboratory tests on rock core are reported. (author)
