泰安市中心城区工程建设适宜性评价
Suitability evaluation of engineering construction in the central urban area of Tai'an
摘要
Abstract
This paper selects terrain and landforms,engineering geology,hydrogeology,adverse geological processes,and geological disasters as the first level evaluation factors,and nine indicators including landform type,ground slope,comprehensive classification of rock and soil properties,foundation soil bearing capacity,site soil type,groundwater depth,groundwater corrosiveness,seismic fortification intensity,and susceptibility to geological disasters as the second level evaluation factors.Based on regional experience,karst collapse disasters are taken as the main control factors to construct an evaluation index system.Using the spatial analysis function of MapGIS,the suitability evaluation of engineering construction in the central urban area of Tai'an is conducted using the evaluation unit multi factor grading weighted index sum method.The results indicate that the research area can be divided into three categories:suitable area for engineering construction,relatively suitable area,and poorly suitable area,and without unsuitable areas.The suitable and relatively suitable areas are widely distributed,accounting for 95.61%of the central urban area.The areas with poor suitability are distributed in the circular area between Jiuzhen-Nanshanggao,accounting for only 4.39%of the central urban area.The overall suitability of engineering construction in the central urban area of Tai'an is good.关键词
