摘要
应用有限差分软件FLAC对含多级粉煤灰子坝的灰坝在开采影响下的破坏规律进行了研究,得到了其所能承受的临界变形值。用有限元程序ANSYS分析了泄洪管、排灰水管和多级跌水斜槽等水工设施在开采影响下的临界变形条件。并将获得的研究成果与某储灰场主要设施的开采破坏情况进行了比对分析,验证了计算方法的可行性和计算结果的可靠性。研究得到的结论和采用的研究方法为储灰场下煤炭资源的开采及储灰场主要设施的维护治理工作提供了技术依据。
The paper studied the destroyed rule of ash dam containing parts of fly ash caused by mining by using FLAC and obtained the critical distortion condition of waterwork structure（discharge pipe,drainpipe,stepped slope,etc） by using ANSYS.The comparison of research conclusion and real destroyed of a power plant showed that the calculation method was feasible and the result was dependable.The research methods and conclusion might provide technical reference for mining under dams and maintaining the structures of ash field.
