摘要
为确保输水隧洞工程运行期的安全,需针对工程特点建立有效的动态监控指标。在分析研究输水隧洞监测方法、工程运行安全影响因素的基础上,选择内外水压力、温度、隧洞衬砌混凝土和围岩变形等影响因子,构建输水隧洞安全监控指标模型,按照置信区间法原理拟定监控指标。将长时段监测数据分段分析处理,同时引入移动平均滤波算法,提出了输水隧洞动态监控指标的拟定方法。实例计算结果表明,所提出的方法能确定测点的动态监控指标。
To ensure the safety of the water conveyance tunnels in the operation period,effective dynamic monitoring indexes should be established according to the engineering characteristics.Based on the analysis of the monitoring methods and the influence factors of operation security,a safety monitoring model of water conveyance tunnel is established.The proposed model considers the influence factors such as internal and external water pressure,temperature,deformation of lining concrete and surrounding rock.The monitoring indexes are determined by the confidence interval method.The long-period monitoring data are segmented and analyzed,and the moving average filtering algorithm is introduced to determine the dynamic monitoring indexes for water conveyance tunnels.The calculation result of an engineering example shows that the dynamic monitoring indexes at measuring points can be determined by the proposed method.
