曹妃甸蓄水池工程地质问题分析与评价
|
摘要
通过对曹妃甸蓄水池区的地质情况、地层空间分布、地基土(尤其是软土层)的物理力学性质、饱和砂土震动液化问题及边坡稳定问题的分析和判别,评价了蓄水池区的工程地质条件和水文地质条件,对主要工程地质问题进行了详细分析和研究,提出了相应地基处理措施或建议,为建筑物设计提供了地质依据,同时也为滨海地区地质勘察提供了借鉴或参考。工程区的软土承载力低,饱和砂土有发生液化的可能性,在地基处理设计时应进行统筹考虑,使工程设计既经济又安全合理。
Based on the analysis and examination of the geology,space distribution of stratum,physical and mechanical properties of soil (especially the soft layer),liquefaction of saturated sand and stability of slope,the paper evaluates the engineering geology condition and hydrological geological condition of Caofeidian Reservoir Area,analyzes the main problems of the engineering geology and applies measures or suggestions for the foundation treatment,all those provide the geological foundation for the structure design. In order to make the design economic and secure,the low bearing capacity of the weak soil and the potential liquefaction of saturated sand in the Project Area should be taken into account.
