随着城市化进程的发展,灌注桩后注浆技术在国内外的应用越来越广泛,灌注桩后注浆是通过把浆液注入地层中,浆液以充填、渗透、挤密和劈裂等方式,挤走土颗粒或岩石裂隙中的水分和空气后占据其位置,浆液固结后将原来松散的土粒或裂隙胶结成一个整体,从而改变岩土体的物理力学性质. 文章将对后注浆前后的土体性质变化进行室内试验,分析得出相关结论与经验.
隨著城市化進程的髮展,灌註樁後註漿技術在國內外的應用越來越廣汎,灌註樁後註漿是通過把漿液註入地層中,漿液以充填、滲透、擠密和劈裂等方式,擠走土顆粒或巖石裂隙中的水分和空氣後佔據其位置,漿液固結後將原來鬆散的土粒或裂隙膠結成一箇整體,從而改變巖土體的物理力學性質. 文章將對後註漿前後的土體性質變化進行室內試驗,分析得齣相關結論與經驗.

Along with urbanized advancement law of development, after the filling pile, the note thick liquid technology is getting more and more widespread in the domestic and foreign applications, after the filling pile, the note thick liquid is through pours into the size in the stratum, the size fills, the seepage, pushes dense and wards off ways and so on crack, after pushing in the earth pellet either the fracture of rock moisture content and the air, occupies its position, after size sohdifying, the original loose soil particle or the crevasse cemented will become a whole, thus change gneiss physical mechanics nature. The artiele will carry on the laboratory test after around the note thick liquid's soil body nature change, the analysis draws the related conclusion and the experience.
