摘要
地质构造对地下水封洞库工程选址、评价及最终施工起着至关重要的作用。本文对锦州地下水封洞库的地质构造及地应力的演化过程进行了分析。在统计分析场区地质构造信息的基础上,运用工程地质力学理论,将场区划分为两个地质构造时期,第一个地质构造时期产生两组(J2、J3)共轭陡节理,最大主应力方向为N7.5°E;第二个地质构造时期产生缓节理J3,最大主应力调整为近似EW方向。通过采用水压致裂法对场区的地应力量测,证实了本文对产区地质构造的演化分析。本文对锦州地下水封洞库及类似工程的建设有较强的指导意义。
Geological structure plays an important role In site selection, evaluation and construction.In this paper,Evolution process of geological structure and stress field for Jin Zhou underground water-sealed Storage Cave are analyzed.On the basis of analysis geological structure information, the area is divided into two tectonic period,and the two groups(J2, J3) steep conjugate joints appear in the first tectonic period, maximum principal stress direction is N7.5 ° E;slow joint J3 appears in the second tectonic period, and maximum principal stress direction is adjusted for nearly EW direction. By In-situ stress measurement with hydraulic fracturing method and the evolution analyzing of the region geological structure is verified.This paper has a strong guiding significance for the jinzhou underground water seal underground or the construction of similar projects.
