天花板水电站厂房后边坡开挖应急处理措施的地质分析

Geological Analysis on the Emergency Treatments of Back Slope behind the Powerhouse of Tianhuaban Hydropower Station during Excavation

天花板水电站厂房后边坡高,工程地质条件复杂,边坡开挖过程中出现了沿层理面开裂、工程监测数据异常等现象。从工程地质条件入手,针对各种异常现象进行分析,采取了有针对性的工程处理措施,效果明显,保障了工程的正常进行。

The back slope behind the powerhouse of Tianhuaban Hydropower Station is high and the engineering geological conditions are complicated. During the excavation of slope, the cracks occurred along the bedding planes and the engineering monitoring data were also abnormal. Taking studies from the engineering geological conditions, the anomalies are analyzed and the treatment measures are proposed. The practical treatments show that the measures are effective and guarantee the construction of project on schedule.
