Appraisals Of Suitability To Project Constructional In New Region In Caofeidian

While the increasing number of cities, the expanding size and the spreading degree of modernization, more seriousness problems about geological environmental engineering and increasing complexity of problems appear in the urban construction projects. Before the programming of region and the selecting site in the urban city, we need to have a full acquaintance about built-up areas. On the one hand, we should take into account the suitability of construction site. On the other hand, we should recognize the adaptability and sensitivity of the project construction site. Through analysing of geological conditions about construction sites and doing the research on geological environmental, we could achieve a reasonable assessment of construction sites.To reach the purpose of the development and utilization we could protect the geological environment to scheme human engineering and economic activities, to control the impact of the geological environment,and to make it more suitable for the production and life of mankind.In this paper, we mostly study the suitability of Project Constructional in New Region in Caofeidian. Before studying engineering geological conditions and geological environment in New Region in Caofeidian, we analyse the area and the surrounding coastal areas of regional engineering geological conditions, discuss the regional geological structure and geological environment in Caofeidian. In accordance with the borehole data, we analyse the distribution and nature of the rock in the study area. Through the establishment of three-dimensional software C Tech geological model, analyzes the study area level of the engineering geological characteristics and the nature of the spatial distribution, to further analysis the building construction site conditions, the physical and mechanical properties of rock, the soil and groundwater conditions , the role of non-performing geological and evaluation in this paper. After analysing and evaluating the data, we select the appropriate rating factor and quantitative evaluation, use qualitative and quantitative method, found fuzzy mathematical model to draw through all of the value of the evaluation unit. Finally, with applicating software ArcView GIS to overlay the results of unit value and using space analysing module to grid computing, this paper divided the study area into appropriate district, less appropriate district, inaptitude district, and not suitable and effective district.Baseing on GIS platform, through the construction site suitability evaluation studies, introducing of fuzzy mathematics to evaluate the zoning process, it could reduce the man-made influence and give a specific value. The result of assessment turns to be much more scientific,objective and accurate. The method is worth promoting in other assessments of urban engineering geological evaluation...
