    基于水波动力学模型对沅江黄埠村滑坡涌浪灾害的数值模拟分析

    NUMERICAL SIMULATION ANALYSIS OF LANDSLIDE SURGE DISASTER IN HUANGBU VILLAGE OF YUANJIANG RIVER BASED ON WATER WAVE DYNAMIC MODEL

    • 摘要: 沅江黄埠村滑坡于2017年6月24日发生,产生的涌浪致使沅江对面多处房屋受损,多人受伤。同时,在滑坡两侧尚有23×104 m3岩土体存在滑塌隐患,可能会造成更大灾害。本文采用水波动力学模型,通过数值模拟的方法对黄埠村滑坡已产生的涌浪灾害进行了复演,并对两侧存在隐患岩土体可能产生的涌浪灾害进行了预测。研究表明,水波动力学模型中奈信模型,适合涌浪模拟。本文在对之前滑坡涌浪复演基础上,验证了模型的合理性,然后对两侧滑坡隐患可能造成的涌浪灾害进行预测,并划分了潜在危险范围,为防灾减灾提供依据。

       

      Abstract: The landslide in Huangbu village of the Yuanjiang River occurred on June 24, 2017. The resulting surge damaged many houses. It also injured many people. At the same time, there are about 230000 cubic meters of rock and soil around the landslide. They may cause greater disasters. In this paper, we used the water wave dynamic model to repeat the surge disaster caused by Huangbu village landslide. Then we predicted what will happen if the rock and soil around slides. The results show that Naixin model is suitable for surge simulation. Affected by heavy rainfall, the landslide in Huangbu village, Yuanjiang River occurred on June 24, 2017, with a landslide volume of 161000m3. The surge caused damage to houses across the river and injured many people. At the same time, there are 230000 cubic meters of hidden dangers on both sides of the landslide, which may cause greater disasters. Therefore, based on the repetition of previous landslide surge, this paper verifies the rationality of the model, then predicts the surge disasters that may be caused by landslide hidden dangers on both sides, and divides the potential risk range, so as to provide a basis for disaster prevention and reduction.
