The Study Of Physical And Mechanical Properties Of Soil And Engineering Geological In Shenyang City Center

With the rapid development of our national economy, the speed of urban construction and development is speeding up, the city scope has broad, all kinds of high-rise, super high-rise building and subway engineering is increasing rapidly, continuously to the direction of the development of deep underground space. This paper made a comprehensive analysis and study on the engineering geological conditions of Shenyang area and provides the reference for engineering survey and design for the foundation, to provide relevant indicators and the characteristic value of subgrade bearing capacity. The purpose is to provide the basis for urban planning, to provide technical support for the engineering construction in the process of survey, design and construction, and provide guidance to urban disaster prevention and mitigation. The main work of this paper includes the following aspects:(1) A comprehensive analysis of the geological structure, Shenyang city center of landform and engineering geological conditions.(2) Collected a lot of engineering geology in Shenyang city center survey data, and physical and mechanical indexes of foundation soil for mathematical statistics, sorting through the test data, lists, mapping and linear regression analysis, linear liquid limit and plastic limit physical property index in the regression equation and cone dynamic penetration test blow count average value and the foundation bearing capacity characteristic value of the linear regression equation.(3) Statistics in Shenyang city center load test, standard penetration test and cone dynamic penetration test data.(4) According to the physical and mechanical properties of shenyang city center soil indicators to determine the characteristic value of subgrade bearing capacity.(5) Analysis the indexes of physical and mechanical properties of soil in the center of Shenyang city,and make a comprehensive evaluation of the engineering geological condition of Shenyang center city, provide a reasonable basis for architectural design.
