水利堤坝工程闸泵区段蚁害隐患模型研究

Study on Ants Hidden Danger Model of Gate Pump Zone of Water Conservancy Dam

水利堤坝水闸和泵站是防汛抢险的重要防守对象,闸泵与坝体衔接的一段范围内容易产生渗漏。白蚁是诱发渗漏的主要因素,本文通过建立堤坝白蚁巢群系统模型和闸泵区的蚁巢群系统及隐患模型,来明确闸泵区白蚁隐患具有近涵闸、多点渗漏、远距离渗漏、渠道渗漏的特性。闸泵区段诱捕和锥探灌浆工程实验均验证了堤坝闸泵区段隐患模型具有合理性,是一种指导防汛抢险的有效模型。

Water gate and pump station of water conservancy dam are important guarding objects on emergency flood fighting. Leakage is easy to happen within the linking range gate pump and the dam body. White ant is the main factor to induce leakage. Through setting up a white ant nest group system model in the dam, and an ant nest group system and a hidden danger model in gate and pump zone, it can be clear that the white ants at the gate and pump zone are featured by sluice gate closing and multi-point leakage, remote leakage, and channel leakage. The inducing and cone probing grouting project tests in gate and pump zone can verify that the hidden danger model of the dam gate and pump zone is reasonable and it is an effective model to guide the flood fighting.
