摘要
玄武岩体是川西南地区水电工程的主要建基岩体 ,其岩体结构受玄武岩体的建造特征及构造改造和浅表生改造的控制。不同地区的玄武岩 ,因岩相及其所处地质地貌环境条件的差异 ,而具有不同的岩体结构特征。该文结合川西南地区大型水电工程 ,根据玄武岩岩相、构造改造和浅表生改造特征及其时空变化规律 。
Basalt is one of the principal rock types used as the foundations of building hydropower engineering projects in southwest Sichuan. Its rock mass structure depends greatly on the lithofacies, tectonic reworking and epigenetic reworking. Variations in the lithofacies and the geological physiological conditions cause the basalts in different areas to have different rock mass structural features. In this paper, the authors evaluate the structural features of basaltic masses in conjunction with large hydropower engineering projects in southwest Sichuan according to the basalt lithofacies, tectonic reworking, epigenetic reworking, and the rule of the space time change.
