Research Of The Features Of Geotchnichnical Engineering And Governing Countermeasures In Zhengzhou City

Based on the study of macro-geology, this paper expounds geotechnical properties, distribution and the features of geotechnical engineering in Zhengzhou. According to many aspects, such as topography and geomorphology, types and distribution of soils or rocks, geotechnical composition pattern and the features of each geomorphic unit zone, geotechnical properties and so on, Zhengzhou urban zone is classified into four geotechnical engineering zones. That's hilly country whose disrupted ground surface has damp and caving loess, vitruvian plain country whose vitruvian field of ground surface is easy to be leveled, oblique plain country which has leveler topography and good bearing layer, and overflowing plain features and differences of geotechnical engineering properties of foundation soil, each geotechnical engineering zone is also classified into different sub-zones of geotechnical engineering. And evaluation is given to geotechnical engineering condition, the suitable ability to buildings and the scheme of foundation in each zone. According to the demands of each building in topography slope, bearing capacity of foundation andgroundwater level and so on, combining with the features of geotechnical engineering of this zone, the builder's field of Zhengzhou urban zone is classified into four types. That's fine field, better field, medium-sized field and worse field. At last, based on the analysis of getechnical engineering condition in Zhengzhou urban zone, analysis and proof is given to some problems of geotechnical engineering which have been already encountered or is likely to encounter in work construction, and prpopose corresponding governing countermeasures.
