Qinzhou Urban Rock Foundation Engineering Geological Zoning Study

In recent years, with the construction of the North Gulf economic zone, Qinzhou-the center city of the gulf ushered in the important opportunity of development. All sorts of investment projects have signed, need of building construction and related infrastructure, thus need expanding the scope of city, the pressure of construction is increasing. The old area of Qinzhou cannot accommodate more architecture and population, there is need a new reserves of construction and project. In order to economic and rational utilization of natural foundation, scientific planning and layout of buildings, reduce the urban construction engineering geological problems of Qinzhou city, it is necessary to research the engineering geotechnical environmental of building's foundation.Based on the study of domestic and foreign cities of engineering geotechnical division results, and on the basis of Qinzhou city of engineering geotechnical environment characteristics of foundation, formulate foundation evaluation index system that appropriate research area of engineering geotechnical environment. Within the framework of the system, to analying in detail city of landform, physicomechanical characteristics, groundwater characteristics, and the related geological disasters in soil foundation, draw the factors as the index of the project, and to provide evidence for urban method using soil foundation engineering geological environment, according to quantitatively evaluate of the posterior probability to draw engineering geotechnical environment in the district foundation division (also called foundation division).The area study of Qinzhou is about 24km2. According to the evaluation results, will distinguish with three kinds of foundation, the good field,general field, and the poor field. Among them, the total area of good foundation' acreage is 3.48km2, account for 14.49%. the total area of general foundation' acreage is 13.20km2, account for 54.99%. the total area of poor foundation' acreage is 7.32km2, account for 30.52%. Finally, from the two aspects of city planning and economic rational selection of building foundation, to table a proposal of good develop of Qinzhou.
