摘要
预可研、可研及施工阶段的地质测绘、钻探、试验等工作揭露了天花板水电站的工程地质条件,就此对坝基工程地质条件及主要地质缺陷进行了分析。根据岩体完整性,结构面的发育特征,岩体风化、卸荷特征及岩体原位测试和声波测试等,对坝基岩体进行了岩体质量类别划分。
By geological mapping, drillings and tests in the stages of pre-feasibility study, feasibility study and construction, the engineering geological conditions in the area of Tianhuaban Hydropower Station are exposed and major geological defects under dam are analyzed. According to rock integrity, structural plane development, rock weathering, unloading features and the in-situ measurement and acoustic testing of rock masses, the rock masses quality of dam foundation are classified.
