延吉经济开发区地质勘察及基础方案分析评价

Analysis and Evaluation on the Geological Survey and Basic Scheme for Yanji Economic Development Zone

本文结合工程勘察实际,查明了延吉经济开发区的地形地貌、地层特征及地下水的埋藏条件,判断了地下水的腐蚀性.根据室内土工试验、标准贯入试验和动力触探等试验成果进行了数理统计及相关计算.结合有关规范与工程地质手册给出了地基承载力特征值,并评价了该地区的天然地基基础方案.

Combined with the engineering investigation practice,the topography,stratigraphic characteristics And the burial conditions of groundwater in Yanji economic development zone were found out and the corrosivity of the groundwater was judged in this paper. Mathematical statistics and related calculation were carried out to the indoor soil were carried out according,standard penetration and dynamic sounding test results. Combined with the relevant specifications and engineering geology handbook,the force characteristic value of foundation bearing was given,and the natural foundation scheme of this area was evaluated.
