介绍： 本隧道进、出口均处于浅埋地段，进口进洞为Ⅲ类围岩，采用Ⅱ式Ⅲ类明洞衬砌。隧道出口围岩破碎、浅埋，采用Ⅳ式Ⅲ类明洞衬砌。整条隧道普遍埋深较浅，且离既有线很近（最近处只有 20m），施工中会互相影响。隧道岩性为灰或深灰色石灰岩。 第一章 总体概况说明 ················································································· 1 一、编制依据····························································································· 1 二、工程简介····························································································· 1 三、气候、水文地质概况 ········································································· 2 四、主要工程项目及数量 ········································································· 2 五、工程竣工日期及计划工期 ································································· 2 第二章 施工总体规划 ················································································· 3 一、隧道施工总体安排 ············································································· 3 二、建立施工管理的组织机构 ································································· 3 （一）管理模式························································································· 4 （二）项目管理组织机构 ········································································· 4 （三）施工队伍的设置及施工任务划分·················································· 5 （四）施工队班组设置及劳动力组织安排·············································· 6 三、隧道施工主要机械设备 ····································································· 7 四、隧道施工进度规划 ············································································· 8 第三章 临时工程及施工准备 ····································································· 9 一、施工总平面布置 ················································································· 9.............
