A geotechnical assessment on moderate risk land would be expected to include: a) Topographic survey (if not already available) or slope profiles. b) A description of the geology and geomorphology of the area, including comment on the areas surrounding the development site. c) Definition of the nature and continuity of the strata over the whole area of land which is proposed to be developed (buildings, access and services) and to a depth below which slipping is most unlikely, by means of test pit and/or drilling and/or augering (unless existing exposures are adequate). d) Assessment of the relative strength and the sensitivity of the soil in each stratum in which, or interface on which, sliding is possible. e) Assessment of likely groundwater levels and piezometric pressures in the strata during extreme infiltration conditions. f) An opinion stated by a geotechnical specialist as to the stability and suitability of the land for development. The stability of the whole slope (upon which the site may only form a part of) and the effects of the development (such as excavation, filling, removal of vegetation, disposal of stormwater or effluent waste water into or over the area) on this should be given.作者: winnie-wu 时间: 2017-8-15 23:03:26
