[Abstract]:With the rapid development of urban engineering economic construction, various kinds of urban geological environment problems become increasingly prominent. Therefore, the quality evaluation of urban engineering geological environment is carried out. It not only has important guiding significance for various kinds of engineering construction suitability planning and construction, but also can effectively realize the full utilization and protection of geological environmental conditions. To realize the mutual coordination between human engineering construction and natural environment. This paper takes the map area of 1: 50 000 towns as the research object, on the basis of field investigation. The quality of engineering geological environment in this area is analyzed and evaluated and the suitability of engineering construction is analyzed and zoned. The main results are as follows: 1. The research area is located in the central and northern east end of Guanzhong basin. It belongs to the continental climate of warm zone. The terrain is flat and the geological structure is simple. The whole area can be divided into five kinds of microgeomorphological units: the first grade alluvial fan in the front of Beishan mountain, the modern alluvial fan in front of the plateau, the first terrace of Weihe River and the high and low floodplain. The surface of the study area is only exposed from Quaternary strata. The main types of engineering geological structure of rock and soil are three types of double layer and 10 kinds of multi-layer. There are 4 faults in the area, which are Lintong-Changan fault, Liquan-Gaoling-Gushi fault. The Qianjian fault and Jiaxinzhuang-Cai Guocun fault in Weinan Plateau, among which the Qianjian fault and Jiaxinzhuang-Cai Guocun fault in Weinan Plateau are Holocene active faults. Changan-Lintong fault and Liquan-Gaoling Gaoshi fault are active faults of late Pleistocene. The neotectonic movement in this area is strong, which is characterized by large scale intermission and differential subsidence. The seismic intensity in the eastern part of Guanzhong basin is 8 degrees, while the rest is 7 degrees. Groundwater resources are abundant in this area. Groundwater is divided into two types: Quaternary alluvium, phreatic phreatic water in alluvial layer and alluvial water in Quaternary, and pore confined water in alluvial layer. The runoff discharge condition in this area is good. 2. The main factors affecting the quality of engineering geological environment in the study area include topography and geomorphology, stratigraphic lithology, bad geological action, groundwater condition and basic earthquake intensity. Geological structure and geotechnical properties, etc., the geological disasters in the study area are rare, the potential engineering geological problems are mainly sand liquefaction, loess soil collapsibility and soil salinization. However, the degree and scope of damage is relatively small. 4. The evaluation of engineering geological environment quality in the area is carried out by AHP, which includes the stability of foundation. Crustal stability and site stability. The stability of foundation and site can be divided into stable areas, which are relatively stable and less stable. The area of foundation stability is about 88.23 km ~ 2, accounting for 21.3km ~ 2 of the total area of study area. The area of the more stable ground area is about 291.68 km ~ 2, accounting for 69.4% of the total area of the study area? The area of poor stability of the foundation is about 40.09 km ~ 2, accounting for 9.5% of the total area of the study area. The area of the site stability zone is about 178.39 km2, accounting for 42.5% of the total area of the study area? The total area of the more stable area is about 92.34 km ~ 2, accounting for 22.0? The total area of the site with poor stability is 149.37 km ~ 2, accounting for 35.5km ~ (2) of the total area of the study area. The analysis of the suitability of engineering construction shows that the suitability of site engineering geological environment in this area is good in general, and the suitable and more suitable area for engineering construction activities is 74.5? The area with poor suitability is only 25. 5? And it is mainly distributed in the area of 500m around the fault and the valley and floodplain area of the Weihe River and its tributaries. Although this area is not suitable for more intense or important engineering construction site. However, it is suitable for the types of land used by planners, such as greening and ecological development.
