在役引水渠道安全稳定性评价与病害治理

Safety Evaluation and Disease Control of Diversion Canal with Concrete Lining in Service

为了全面分析大型灌区在役引水渠道的安全稳定性,并给出可靠的病害治理方案,针对大型灌区引水渠道普遍存在病害现象,以焦作市引沁灌区河口段引水渠道为工程实例,使用现场检测和数值模拟方法,对该引水渠道进行了安全稳定性综合评价,并提出具有针对性的病害治理方案。研究结果表明,运用现场检测、静动力数值模拟分析方法能够更加科学地评价大型灌区引水渠道结构安全稳定性。

In order to analyze comprehensively the safety and stability of the water diversion channel in service in large⁃scale irrigation area,and to provide a reliable disease control scheme,aiming at the diseases commonly in the diversion canal in large⁃scale irrigation area and tak⁃ing the diversion canal of Yinqin irrigation area in Jiaozuo City as an example,the in⁃situ quality inspection and numerical simulation were made in the diversion canal,and then comprehensive evaluation was made on the safety and software of the diversion canal,while a targeta⁃ble strengthening disease control scheme was put forward.The research results show that the method combining in⁃situ inspection and analysis with numerical simulation of the static and dynamic statuses can evaluate the overall safety and stability of the diversion canal structure more scientifically.
