烟台市福山区姜家夼泥石流隐患点特征分析与预测
|
摘要
泥石流灾害的发展趋势取决于泥石流形成条件的变化和人类经济活动的合理程度。从泥石流形成的自然条件分析,地质地形条件是相对稳定的,在相当长的时期内不会发生大的变化,降水活动则是一个变量,并且具有突发性;人类经济活动在相对较短的时间内变化不大。因此,决定泥石流活动趋势的因素主要是降水等基本条件。本文通过对姜家夼地区泥石流的资料收集和研究分析,阐明灾害点发育的自然环境、形成条件、灾害体的基本特征和威胁对象,为地质灾害防治方案的选择和防治工程的设计提供基础资料。研究表明,现阶段姜家夼地区泥石流的发展阶段处于发展期,泥石流灾害将趋于相对稳定,但一旦遭到大暴雨、特大暴雨的作用,可能会再次引发泥石流灾害。
The development trend of debris flow disasters depends on the changes in the formation conditions of debris flows and the reasonable degree of human economic activities.From the analysis of the natural conditions formed by the debris flow,the geological and topographic conditions are relatively stable,and they will not change greatly for a long period of time,while the precipitation activity is a variable and sudden;In addition,the human economy activities do not change much in a short period of time.Therefore,the factors determining the trend of debris flow activity in the survey area are mainly the basic conditions such as precipitation.Based on the data collection and research analysis of debris flow in Jiangjiakuang area,this paper clarifies the natural environment,formation conditions,basic characteristics and threat objects of disaster sites,and provides basic information for the selection of geological disaster prevention programs and the design of prevention and control projects.Studies have shown that at this stage,the development stage of debris flow in Jiangjiakuang area is in the development stage,and the debris flow disaster will tend to be relatively stable.However,once it is affected by heavy rain and heavy rain,it may cause mudslide disaster again.
