Abstract: Jinan city is famous for its history and culture as the capital of Shandong provience. With the rapid urbanization, the engineering-geological and environmental problems become more and more acute. It is important to make classification and evaluation of engineering-geological-environmental quality of rock-soil foundation for the city construction. This paper analyzes the engineering-geological environmental conditions and sets up a model and determines its preferred indices for the classification and evaluation of engineering-geological-environmental quality of rock-soil foundation in Jinan area by using a BP neural network.
