摘要
通过工程地质分析,监测资料分析和有限元数值模拟分析对铜湾水电站左岸船闸高边坡的长期稳定性进行分析与评价,并通过计算结果与实测资料对比,验证了计算结果的可靠性。分析结果表明:开挖后边坡不存在整体稳定问题;边坡的潜在危险区域主要在Z0+70.0桩号附近,降雨时边坡的稳定性明显降低;边坡满足长期稳定的要求。建议加强坡体排水,注意坡面防渗。
By engineering geological analysis, monitoring data analysis and finite element analysis of numerical simulation, the long-term stability of the lock high slope on the left bank of Tongwan Hydropewer Station is analyzed and estimated, and through comparing with the measured data, the reliability of the calculated results is verified. The results show that there is no problem of overall stability of the slope after excavation; the slope＇ s potential danger zone is mainly in the vicinity of Z0 ＋ 70.0, the slope＇ s stability is decreased significandy when rainfall; and the slope can meet the requirements of the long-term stability. Then some proposals are put forward to strengthen the slope drainage and prevent the slope seepage.
