摘要: 针对宜万铁路16标段三岔口大断面隧道的特殊复杂地质条件:隧底节理裂隙异常发育,溶蚀严重,岩体破碎夹 泥,且有多处不规则岩溶等情况,采用钢花管注浆对隐伏岩溶、溶槽、破碎带进行加固处理,通过注浆钻心取样评定 检查,该段基底承载力达到了设计要求,有效避免了雨季施工产生涌水、突泥岩层产状较缓和因岩溶带来的安全隐患.

Abstract: The tunnel with large section of the 16th Section in YI WAN Railway is in the special geological conditions.including joinfing fissure developing abnormally,dissolution being very seriously,the rock mass cmshing and many place having abnormity fissure,and 80 on.To minfome and treatment these,the special groutings to fissure,solution groove and some place of berak were advised.At last,assessed by samplings,this carrying capacity in fundus reached the design request,and efectivdy defensed the gushing water,the sudden mud-rock strike-dip moderating production proem and the hidden trouble of safety.

Key words: tunnel, foundation base, karst, grouting, construction
