摘要:
"5·12"大地震后,灾区泥石流灾害发生频率明显升高。为消减灾害影响、减少损失,现已对灾区大部分易发性泥石流沟进行了治理。在泥石流的防治工程中,拦挡坝是一种应用比较广泛的措施。相比于传统的直线型重力拦挡坝,本文结合塘房沟泥石流形成的地质条件,提出并应用翼墙型拦挡坝在泥石流的防治工程中。本文利用有限元软件ANSYS对翼墙型拦挡坝在泥石流整体冲击力作用下进行了数值模拟计算,分析了拦挡坝的变形和受力特征。最后结合拦挡坝的数值模拟计算结果,为保证拦挡坝的长期有效性,对其进行了结构设计优化,研究成果可为相似泥石流防治工程提供借鉴。
Abstract:
The frequency of debris flow disaster in the disaster area is significantly increased after the "5·12" earthquake. In order to reduce the impact of disasters and economic losses, most of the prone debris flows have been treated. Retaining dam is a widely used measure in the prevention of debris flow. Firstly, this paper propose and apply the wing wall type dam against debris flow based on the geological conditions of Tangfanggou debris flow compared to the traditional linear type gravity dam. Then finite element software ANSYS is used to simulate and calculate the wing wall type dam under the overall impact of debris flow, and analyzed the deformation and force characteristic of the dam. Lastly, the dam was optimum designed combined with numerical simulation results in order to ensure the long-term effectiveness of the dam, and the research results can provide reference for similar engineering prevention of debris flow.
