水库浸没灾害调查与评价方法研究

水库浸没灾害调查与评价是为浸没范围确定、浸没灾害研究、浸没态势预测提供数据基础，但在具体工作中缺少简便可行的调查与评价方法。为此，结合实际工作经验总结了一套浸没调查方法（研究范围选取、测点布设原则、浸没监测及浸没调查实施方案）与相应的浸没评价方法（确定时空范围、确定地下水临界深度、浸没灾害分区），并以大顶子山水库上游浸没区分区评价为例对该方法进行了实际运用。运用该方法得到了大顶子山水库的浸没现状评价分区，为研究大顶子山水库浸没问题提供了科学依据。

Study on investigation and evaluation method of reservoir inundation disasters:case of inundation - affected area on the upstream of Dadingzishan Reservoir

The investigation and evaluation of reservoir inundation disasters can provide data for inundation area determination,inundation disaster study and inundation trend prediction,so,a feasible and convenient method is needed in the practical work.An investigation method of inundation(including selection of study area,principle of measure points setting and implement scheme of inundation monitoring and investigation) and the corresponding evaluation methods(including determination of temporal-spatial range and critical depth of underground water and partition of inundation disaster) are summarized on the basis of practical experience.The method is applied in the partitioned evaluation of inundation-affected area on the upstream of Dadingzishan Reservoir.The partitioned evaluation of inundation situation of Dadingzishan Reservoir is obtained,providing scientific basis for the study of reservoir inundation of Dadingzishan Reservoir.
