地震海啸驱动方向和破坏力探讨
|
摘要
基于诱发地震海啸的核心——"能量"、"动态波"、"介质载体"演化融为一体的延续性跟踪分析思路,引出了对海啸波起转折导向作用的"水跃"概念,为解释海啸驱动方向转移和破坏威力的量化分析缀出了系统理论和方法,并为减轻海啸破坏提供了"断链减灾"的可循途径。
A concept of "hydraulic jump" with a turning directing effect on tsunami wave was introduced based on the sustainable tracking analysis idea integrating "energy","dynamic wave" and the evolution of "medicating carrier" which are all the core concerns in the research of earthquake-induced tsunamis.It provides a system theory and approach for quantitative analysis to explain the driving direction shift and destructive power of tsunamis,as well as a traceable way of "chain-cutting disaster mitigation" for reducing the damages of tsunamis.
