Abstract
This paper takes the immersion embankment project of the Dadushan Reservoir section from K0+940 to K1+460 in the East Ring Road Project of Yongxin County,Ji'an City,Jiangxi Province as a case.Aiming at the construction problems of seasonal immersion embankments under complex geological,hydrological and climatic conditions,a three-dimensional theoretical framework of water-force coupling,unsaturated soil mechanics and freeze-thaw cycle has been constructed.The collaborative reinforcement technology of base stone throwing for silt removal and waterproofing retaining wall is proposed.The silt is replaced by layer-by-layer throwing and filling of graded block stones,and the seepage is blocked by setting up deep mixed cement soil waterproofing retaining wall.The construction parameters are optimized through orthogonal tests.Engineering practice shows that this technology increases the bearing capacity of the foundation by 275%,keeps the total settlement within 10cm,significantly reduces the risk of water damage,shortens the construction period by 27%,and lowers the comprehensive cost by 22%.The research results provide scientific and feasible technical solutions and practical references for similar projects.关键词
