山东省水资源严重匮乏,多年平均径流量229亿m~3。已建水利工程拦蓄水量63.1亿m~3,有72.4％的水量不能充分拦蓄。在目前条件下修建地上水库比较困难,而修建地下水库不增加淹没移民,安全可靠,投资少。因此,在有地下蓄水条件的地方修建地下水库是今后水利工程发展的方向。 我省沿海地区的地下水库坝 Shandong Province, a serious shortage of water resources, the average annual runoff of 22.9 billion m ~ 3. Built water conservancy project to save water 6.31 billion m ~ 3, 72.4% of the water can not be fully intercepted. Under the current conditions, it is more difficult to construct the aboveground reservoir, while constructing the underground reservoir will not increase the inundation of immigrants, which is safe and reliable with less investment. Therefore, the construction of underground reservoirs where underground water storage conditions are the future direction of water conservancy project development. Underground reservoir dam in the coastal area of ​​our province
