| 摘 要： | 分级分期灰渣筑坝是近年发展起来的山谷贮灰场建设的一种新型技术,是为了满足燃煤电厂贮灰年限和调节洪水的要求的一种新型设计.为满足分级分期灰渣筑坝的设计要求,分析评价初期坝的稳定性与先期粉煤灰灰体堆积特征是构筑分级子坝的重要基础.本文通过水文地质及工程地质调查与岩土工程勘察探讨了麻地湾灰场子坝加高所涉及的相关岩土体的工程地质特征与场地水文地质特征,据此对分级子坝加高的工程地质条件进行了适宜性评价,并通过对堆积灰体物理力学试验分析了粉煤灰灰体的堆积特征与压实程度,为子坝加高设计提供了可靠参数.

| Abstract: | A new technique of fly ash for sub dam, which is a new type dam for storage of fly ash produced by coal power station, is developed in valley fly ash field. A basic study for sub dam construction is the assessment of safety of the primary dam and the characteristics of deposited fly ash. The hydrogeological and engineering geological patterns of the rock and soil mass relative to the sub dam is addressed through geological survey and geotechnical drilling, and the engineering geological conditions for sub darn is assessed. The physical mechanics and compressibility of fly ash are discussed, and physical mechanics parameters for sub dam design are recommended. |
