【摘要】：随着我国国民经济的迅速发展,城市建设发展速度也随之加快,城市范围不断扩大,各类高层、超高层建筑以及地铁工程等迅速增加,地下空间不断向深大方向发展。本文对沈阳中心城区工程地质条件进行综合分析和研究,为工程勘察提供参考资料,并为地基基础设计提供相关指标和地基承载力特征值。目的是为城市规划提供依据,为工程建设过程中的勘察、设计以及施工提供技术支持,对城市防灾减灾提供指导依据。本文所做的主要工作有以下几方面：(1)综合分析了沈阳中心城区工程地质分区、地形地貌、工程地质特征以及沈阳地铁一号线沿线工程地质特征。(2)收集大量沈阳中心城区工程地质勘察资料,并对地基土的物理力学性质指标进行数理统计,通过整理试验数据、列表、绘图并进行线性回归分析,得到物理性质指标中塑限和液限的线性回归方程以及圆锥动力触探试验击数平均值和地基承载力特征值的线性回归方程。(3)统计沈阳中心城区载荷试验、标准贯入试验及圆锥动力触探试验数据。(4)根据沈阳中心城区土的物理力学性质指标确定地基承载力特征值。(5)综合分析沈阳中心城区土的物理力学性质指标,对沈阳中心城区的工程地质状况作出综合评价,为建筑设计提供合理依据。
[Abstract]:With the rapid development of our country's national economy, the speed of urban construction is also speeding up, and the urban scope is constantly expanding, and all kinds of high-rise buildings, super high-rise buildings and subway projects are increasing rapidly. The underground space continues to develop in the deep direction. This paper makes a comprehensive analysis and research on the engineering geological conditions in the central city of Shenyang in order to provide reference materials for engineering investigation. The purpose of this paper is to provide the basis for urban planning, to provide technical support for the investigation, design and construction in the process of engineering construction, and to provide the relevant indexes and foundation bearing capacity characteristic values for the foundation foundation design, the purpose of which is to provide the basis for the urban planning. The main work of this paper is as follows: 1) Comprehensive analysis of engineering geological zoning, topography and geomorphology in Shenyang central urban area, Engineering geological features and engineering geological features along Shenyang Metro Line 1) collect a large number of engineering geological survey data in Shenyang central urban area, and carry out mathematical statistics on the physical and mechanical properties of the foundation soil. Through sorting out the test data, the list is given. Drawing and performing linear regression analysis, The linear regression equation of plastic limit and liquid limit in physical property index and the linear regression equation of the average stroke number of cone dynamic penetration test and the characteristic value of foundation bearing capacity are obtained. The standard penetration test and cone dynamic penetration test data. 4) based on the physical and mechanical properties of the soil in Shenyang central urban area to determine the foundation bearing capacity characteristic value. 5) to comprehensively analyze the physical and mechanical properties of the soil in Shenyang central urban area. The comprehensive evaluation of the engineering geological condition in Shenyang central city provides a reasonable basis for architectural design.
