去年8月上、中旬,沂沭泗流域出现了1974年以来的两次较大洪水,暴露了水利工程存在的严重问题和管理工作中的薄弱环节。从中总结和吸取经验教训,对夺取今年防汛工作胜利,有重要借鉴作用。沂沭泗工程标准低、质量差、隐患多。统管几年来,虽做些了基建和岁修工程,防洪能力有所提高,但并未彻底解决问题,加上大部分堤防均是1974年以后加固的,没有经受过洪水考验。因此,当“90.8”两次洪水发生后,致使部分工程出现渗水、雨淋冲沟、堤防漏洞、裂缝、滑坡和险工塌岸等较大险情。洪后反思,出现这些险情的原因是多方面的:(1)石护岸基础的设计深度偏小,很多石护岸都在两次洪水中冲坏基础;(2)以前的培堤工程考虑不全面,没有处理基础,给堤防加固留下 Last August, in the middle and mid-Yishusi watershed, two major floods occurred since 1974, revealing serious problems in water conservancy projects and the weak links in management. From the summary and lessons learned, to win this year’s flood control victory, there is an important reference. Yishusi engineering standards low, poor quality, many hidden dangers. Over the past few years, despite the infrastructure and out-of-date construction projects, the improvement of flood control capabilities has not completely solved the problem. Most of the dikes have been reinforced since 1974 and have not undergone flood tests. Therefore, when the floods of “90.8” took place, some major projects resulted in water seepage, rain and gully erosion, embankment loopholes, cracks, landslides and dangerous collapses of dangerous vessels. Reflections after the flood, there are many reasons for the emergence of these dangerous situations: (1) The design depth of the stone revetment foundation is too small, and many stone revetments have broken the foundation in the two floods; (2) The inadequate consideration of the previous dikes embankment project , Did not deal with the foundation, leaving the embankment reinforcement
