【摘要】：隨著我國國民經(jīng)濟的迅速發(fā)展,城市建設發(fā)展速度也隨之加快,城市范圍不斷擴大,各類高層、超高層建筑以及地鐵工程等迅速增加,地下空間不斷向深大方向發(fā)展。本文對沈陽中心城區(qū)工程地質條件進行綜合分析和研究,為工程勘察提供參考資料,并為地基基礎設計提供相關指標和地基承載力特征值。目的是為城市規(guī)劃提供依據(jù),為工程建設過程中的勘察、設計以及施工提供技術支持,對城市防災減災提供指導依據(jù)。本文所做的主要工作有以下幾方面：(1)綜合分析了沈陽中心城區(qū)工程地質分區(qū)、地形地貌、工程地質特征以及沈陽地鐵一號線沿線工程地質特征。(2)收集大量沈陽中心城區(qū)工程地質勘察資料,并對地基土的物理力學性質指標進行數(shù)理統(tǒng)計,通過整理試驗數(shù)據(jù)、列表、繪圖并進行線性回歸分析,得到物理性質指標中塑限和液限的線性回歸方程以及圓錐動力觸探試驗擊數(shù)平均值和地基承載力特征值的線性回歸方程。(3)統(tǒng)計沈陽中心城區(qū)載荷試驗、標準貫入試驗及圓錐動力觸探試驗數(shù)據(jù)。(4)根據(jù)沈陽中心城區(qū)土的物理力學性質指標確定地基承載力特征值。(5)綜合分析沈陽中心城區(qū)土的物理力學性質指標,對沈陽中心城區(qū)的工程地質狀況作出綜合評價,為建筑設計提供合理依據(jù)。
[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.
