应用聚脲技术实现地震次生灾害的防御

研究地震诱发的次生灾害的防御技术,对于保障人民生命及财产安全具有重大的意义。本文全面介绍了聚脲技术在崩塌、滑坡及泥石流(以下简称崩滑流)和遇难者遗体掩埋等地震次生灾害中应用的技术优势,简要分析了地震次生灾害的类型和危害性,详细探讨了聚脲技术在崩滑流边坡防护和遇难者遗体掩埋等地震次生灾害应用中的施工工艺。研究表明:(1)聚脲技术因具有优异的力学性能和抵抗水流冲蚀磨损的性能,能有效地防止雨水对边坡的淘蚀,从而增加边坡的稳定性,预防崩滑流等地质灾害的发生;(2)聚脲技术突出的防腐抗渗性能及整体封闭效果和超长耐候性能可对遇难者的遗体进行妥善掩埋,达到隔离水源、保护环境的目的。

Polyurea Technology Applied to Post-earthquake Disasters for Defencing

Researching in post-earthquake disasters defense technology to ensure the people’s life and property security has significant meaning.In this paper,the advantages of polyurea technology in collapse,landslide,mud-rock flow and victims buried in post-earthquake disasters are introduced,the types and dangers of post-earthquake disasters are briefly analyzed,and the polyurea technology application construction is discussed in detail.Research shows that:(1)Polyurea technology has excellent mechanical properties and anti-scour performance,can effectively prevent the rain from washing the slope so that increase the stability of the slope,hold back geological disasters occur.(2)The outstanding anti-corrosive,anti-permeability,overall protective and ultra-long ageing resistant performances of polyurea technology can make the victims for proper burial to isolate water source,and protect the environment.
