留预埋工程）施工，左线里程ZK38+790〜ZK39+691（全长901m）,右线起

止里程K38+790〜K39+698（全长908m）0

2工程概况

工程自然条件

x新隧道位于巧家县境内，为分离式隧遒，拟建隧道呈曲线展布，隧

道进口段轴线方向约357°,出口段轴线方向约323°；左线隧道起讫桩

号ZK38+790〜ZK39+691,总长901m,隧道最大埋深约230.98m,位于

ZK39+180处；右线隧道起讫桩号K38+790〜K39+698,总长908m,隧道

最大埋深约236.66m,位于K39+190处，属于中长隧道。

巧家县地处云贵低纬高原，金沙江河谷深切割地带，海拔高差大，地

形地貌复杂，构成了典型的山区气候特点，属南亚热带到寒温带均有分布

的高原立体气候，具有“一山分四季，十里不同天”（℃七（七七；降水

量分布特点是：雨季（5—10月）多年平均为736.5mm,占全年降水量的

89.5乐干季（11—4月）多年平均降水为86.2mm,占全年降水量的10.5%,

最大一日降水量达109.9mm；多年蒸发量达2529.3mm；光照条件：多

年平均日照时数2134.2小时，3月最多，为249.1小时，9月最少，

为120.1小时。

x新隧道所在地区属高中山地貌，地形起伏较大。隧道范围内o线高

程870.37m〜895.53m,最大高差约25.16m。山体自然坡度30°〜45°，

植被较发育。进、出口处于山前斜坡地带，山坡处于基本稳定状态。隧址

区进出口均没有道路，通行条件较差。

隧址区地表水主要为双河和金沙江水体，位于线位下方，对拟建隧道

无影响。地下水主要为基岩裂隙水，主要分布在玄武岩风化裂隙中，节理

裂隙发育，连通性一般，赋水条件一般，浅部强风化岩风化裂隙发育，岩

体破碎，含少量裂隙水，主要靠大气降水补给，冲沟等低法部位以地下径

流形式排泄；斜坡部位以沿裂隙渗流形式或受地形切割排出地表。地下

水主要靠大气降水及地表水入渗补给，由于区内地下水动态受降水影响,

变化较大，雨季施工时隧道涌水量可能有较大的增幅。

X新隧道属中长隧道，左线里程ZK38+790-ZK39+691(全长901m),右

线起止里程K38+790-K39+698(全长908m),隧道单幅合计1809m,其中洞

身IV级围岩占66%,V级围岩占34双隧道左右线进出口均为端墙式洞门。

隧道进口段置于坡积碎石土，围岩主要为强风化灰岩，岩体中风化裂

隙极发育，多呈张开〜微张，岩体破碎，围岩整体强度及稳定性差。隧道

出口段仰坡岩土体由坡积碎石土、强〜中强风化玄武岩组成。强风化玄武

岩，岩体中风化裂隙极发育，多呈张开〜微张，岩体破碎。洞身段崩坡残

积层及强风化玄武岩：围岩级别为V级，围岩稳定性差；强风化〜中风化

玄武岩：围岩级别为W级，围岩稳定性较差。

K38+790(ZK38+790)〜K39+167(ZK39+167)属于连拱隧道;K39+167

(ZK39+167)〜K39+500(ZK39+496)属于超小净距隧道；K39+500

(ZK39+496)〜K39+698(ZK39+691)属于小净距隧道;隧道设计人行横

通道2处。

2.3不良地质作用及特殊性岩（土）

根据钻探及地质调绘、物探资料，隧址区地形起伏较大，上覆少量的

第四系，下伏强风化玄武岩，岩体破碎。
