Suitability Research On Geological Environmental Constuction Of Beizhai, Wanggezhuang And Shazikou In Laoshan District Of Qingdao.

The paper selects Bei Zhai, Wang Gezhuang, and Sha Zikou, the three towns in the process of urbanization, as the study area of the suitability of engineering projects affected by geological environment. Combined with various terrain, topography, bedrock, engineering geology, hydrogeology, characteristics of flood and geological hazards, the study area is divided by suitability assessment of engineering, adopting GIS technology and quantified multi-factor evaluation method, which provides a reference for the urban scientific planning from the perspective of the geological environment.There were Pi Shikou- Fushan geological fault and Wang Gezhuang-Shan Dongtou geological fault in Wang Gezhuang Town area. The main causes of landscape topography are fluvial landform and the sea water into the landscape; Engineering Geology Division also loose mountain valley area; main geological hazards and risks are collapse. Study shows Wang Gezhuang suitable building area 25.76km~2, accounting for 58.9%, conditional construction suitable area 10.02km~2, accounting for 22.8%, development and construction of suitable area 8.01km~2, accounting for 18.3%.There were Pi Shikou- Fushan geological fault and Bai Shahe geological fault in Bei Zhai Town area, and both are water landscape by cause. Topographic types are mainly hills, mountains, valley fill areas, engineering geology type is dominated by mountain areas for the loose Valley Lord, and geological hazards and risks are collapse and the development of debris flow. Based on the study, the North residential area of suitable construction 2.48km~2, accounting for 23.7%, conditional construction suitable area 5.07km~2, accounting for 48.4%, development and construction of suitable area 2.09km~2, accounting for 27.9%.Sha Zikou town is divided by the causes of landscape topography into fluvial landform and the sea water into the landscape, to the main mountain valley fill area. Engineering Geology Division is dominated by mountain valley fill areas. High-risk flood areas are mainly located in the Liangshui River downstream, and the main types of geological disaster contain the landslide hazards and the development of collapse. Study shows the Shazikou suitable building area 7.13km~2, accounting for 68.4%, conditional construction suitable area 2.94km~2, accounting for 28.2%, development and construction of suitable area 0.35km~2, accounting for 3.4%.
