洮儿河灌区满洲岱渠首浸没问题分析

摘要

洮儿河灌区满洲岱渠首蓄水后，渠首附近村庄、农田可能产生一定的浸没影响，将给人们的生产生活带来危害。根据满洲岱枢纽地形地貌条件，拟采用定性与定量分析相结合的方法，对不同水位运行条件下渠首周围可能出现浸没问题进行预测评价，提出可能浸没的范围及程度。并对浸没产生的影响要素进行分析，影响因素为工程地质、水文地质、水文气象、人为活动等条件。其中水文地质条件中的地下水位的变化为主要因素。%It might influence the village and farmland nearby headwork and harm people’s living,after the impoundment of Manzhoudai headworks of Yaoer river irrigation area. According to geographic and geomorphic conditions of Manzhoudai hinge,the immersion problem under different operation water level was forecasted and evaluated,and the method of combination of qualitative and quantitative analysis was adopted,then the possible scope and degree was proposed. After that,the influential factors from im-mersion were analyzed,which were engineering geology,hydrogeololgy,hydro meteorology,human activity,and so on. The change of underground water level among the condition of hydrogeololgy was the main influence.
