哈尔滨大顶子山航电枢纽工程蓄水后引起的浸没地质灾害研究

哈尔滨市松北区大顶子山航电枢纽工程蓄水后，哈尔滨段的江水位将常年保持在116m，比枯水期水位高出6m多。届时势必要引起松北区地下水水位的壅高，导致发生区内浸没问题。利用GMS（地下水流模拟系统）软件中SOLID模块，采用钻孔间插值法建立松北区含水系统三维立体模型，进行地下水壅高计算，给出地下水位临界深度，确定研究区内浸没范围；进行浸没评价，提出浸没危害治理工程措施。

Study on submerged geologic hazard of navigation power key project by sluice in Dadingzishan of Harbin

The water level for Harbin reach will be kept on 116 m after Dadingzishan navigation power reservoir in Songbei district of Harbin begins to store water, which will be 6 m higher than that in dry season in the past. That time the result must cause the back-up groundwater level rising in Songbei district and immersion problem. By using SOLID module of GMS software and interpolating method between the drills, the three dimensional model containing water system in Songbei district was established. The author calculated the back-up water level, found the critical depth, determined the immersion scope, conducted immersion assessment and put forward the control measures for the immersion hazard.
