八宝海水库始建于１９５６年８月，１９５８年６月竣工。枢纽工程由主坝，一、二、三号副坝，溢洪道．输出洞等级成。主副坝均为匀质土坝。该水库兴建时由于没有对坝基做防渗处理，主观基中有３～５ｍ厚的砂砾石层，自水库畜水后一直存在着严重的渗漏问题，危及着大坝的稳定安全．经研究对主副坝坝基进行防渗灌浆处理。帷幕位置在坝轴线基础之下；帷幕型式主、副坝一律采用单排直线型悬挂式；灌浆深度主坝控制在建基面以下１５ｍ左右，一、二号副坝控制在建基面以下１０～１２ｍ；灌桨控制标准以岩石单位吸水量ｗ值为０．１Ｌ／（ｍｉｎ·ｍ·ｍ）．经过对防渗处理后的主、副坝坝基进行检测分析，大坝坝基渗漏问题得到明显的控制。
Babaohai Reservoir was built in August 1956, completed in June 1958. The hub project consists of the main dam, the auxiliary dam of No. 1, No. 2 and No. 3, and the spillway. Output hole level into. The main dam are homogeneous earth dam. Since the dam foundation is not seepage control during the construction of this reservoir, there are 3 ~ 5m thick sand and gravel layers in the subjective base. Since the water of reservoirs has been in existence, there is a serious leakage problem, endangering the stability and safety of the dam. After studying the main and auxiliary dam foundation impervious grouting treatment. Curtain position of the main axis of the dam; curtain type main and auxiliary dams will be used in a single row linear suspension; grouting depth control of the main dam below the base surface of about 15m, No. 1 and No. 2 auxiliary dam control in the foundation below 10 ~ 12m; paddling control standard rock unit water absorption w value of 0.1L / (min · m · m). After the seepage control treatment of the main and auxiliary dam foundation for testing and analysis, dam foundation seepage problems have been significantly controlled.
