某抽水蓄能电站工程区断裂断层泥研究

Application of Fault Gouges from the Site of A Pumping Storage Power Station

通过断裂断层泥的粒度成分分析、粒度分形和石英颗粒形貌(SEM)特征观测等方法来分析与评价某抽水蓄能电站工程区断裂活动性,从而得出工程的稳定性。这一研究对大型地下工程场区稳定性综合论证及对地下硐室合理选址、设计以及确保工程安全等具有重要的应用价值。

Based on analysis of grain distribution, the granularity fractal dimension of fault gouges and the special micro structural features of quartz in fault gouges from the site of one pumping power station are discussed. And the activities and age of faults are calculated in the engineering area, the effects of the fault activities in primary workshop site on the regional stability are obtained. The analysis of fault activity plays an important role in evaluation of regional stability in underground engineering, and selecting appro priate site designing tunnel and ensuring the safety of underground engineering.
