目前,渠道填方坝在渠道运行中出现的险情占工程险情总量的90.0%以上,而填方坝工程险情又是灌区工程运行中普遍存在的,要想让基层管理人员在广泛的填方坝工程险情中及时、准确地判断出险情发展速度及危险程度,并及时采取相应的预防措施,是灌区渠道运行安全管理的重中之重。基于此,针对东一干目前存在的工程险情,就渠道填方坝渗漏分类及变化过程、填方坝险情观测、险情预防及补救三方面进行详细论述,提出一整套填方坝险情观测、预防、抢修补救的方法措施,可操作性强,对于加强工程管理,预防填方坝突发工程险情有着“提前发现、提前预防”的重要意义,对于同类灌区有实用推广意义。
At present, the channel dams in the channel operation of the dangerous situation accounted for more than 90% of the total project risk, while the filling dam project danger and irrigation project operation is ubiquitous, in order to make grass-roots management personnel in a wide range of fill Dam project in a timely manner to accurately and accurately determine the dangerous speed of development and dangerous levels, and timely take appropriate preventive measures, irrigation canal operation and safety management of the top priority. Based on this, aiming at the existing engineering danger in East China Plain, this paper discusses in detail the classification and change process of seepage leakage of channel fill dam, the dangerous situation of fill dam and the prevention and remedy of dangerous danger. , Methods and measures for repairing and remedying are strong and can be practically used. It is of great significance for strengthening project management and preventing dangerous accidents of embankment dam projects.
