1、工程概况
鸡丑山隧道位于鸡丑山越岭段，原有省道215线为克服高差，多次回头展线，且高海拔地区，受冰雪期、雾期及冻土路基影响较大，行车安全性较差。本次改建采用2745m的长隧道穿过，既降低了原路海拔约300m，，又避开了冰雪及雾区期较长的路段。
隧道进洞口表层为第四系全新统残坡积的碎石，岩体裂隙发育，部分裂隙泥质充填，钻孔见裂隙为石英脉充填。隧道挂扣、成洞条件差，地下水活动较弱，洞室一般潮湿，雨季施工时有滴水或线状水流。
隧址区属青藏高原气候，夏季温和、冬季寒冷。多年平均降水量906mm，一般集中在6—9月；年平均气温1.1℃，1月平均气温＜-7℃，无霜期约90天。 2、编制依据

5、施工工艺与流程
5.1 施工顺序
首先在洞顶人工挖截水沟，并根据施工图设计要求进行铺砌浆砌片石，把雨水引出洞口施工作业区外。
5.2 具体施工步骤
（1）在开挖的边仰坡边线外5m，由测量组进行截水沟中线定位。 （2）按放好的中心线进行截水沟开挖，开挖净空符合设计要求。
（3）铺砌或混凝土浇筑之前，对边沟、截水沟进行修整，保证沟底和沟壁坚实平整，沟底标高及断面尺寸符合图纸要求。
（4）按要求铺设砂砾垫层，并夯压密实。
（5）沿沟壁纵向挂线，先铺砌沟底，再铺砌侧壁，保证铺砌时座浆饱满、沟缝平顺，铺砌成型的排水沟平整密实，沟底顺畅，不积水，并注意与洞口其它排水系统相结合，合理导流。 6、质量保证措施
测量（指中线与高程）控制的结果，除了直接影响到工程质量，还将直接影响建设成本和单位信誉。为此，我们将利用洞外导线点，实现洞门位置的准确，路基边坡放坡的准确。 7、安全保证措施
（1）严格执行安全管理制度，从管理上确保安全措施的落实。 （2）在高于3m的坡面上作业，必须挂安全绳。
（3）各种施工机械必须制定相应的、详细的操作规程，并严格执行。夜间作业时，应有足够的照明设备。

（4）严禁截水沟和下方其它工程同时施工。 8、环境保护措施
为了保护和改善生活环境与生态环境，防止由于隧道施工造成的作业污染和扰民，保障工地附近居民和施工人员的身体健康，努力做好环境保护工作。
8.1组织措施
施工期间对环境进行保护是业主对承包商的要求，也是承包商的自身职责。根据公司管理标准、国家省市规定、业主要求，结合工程的具体情况制定本工程《环境保护实施细则》，以细则的各项具体规定作为统一和规范全体施工人员的行为准则。
同时，委派专门的环境保护工作人员，全面负责本项目的环境保护工作。
加强环保教育和激励措施，把环保作为全体施工人员的上岗教育内容之一，提高环保意识。对违反环保的班组和个人进行处罚。
8.2防止大气污染措施
（1）清理施工垃圾时使用容器吊运，严禁随意临空抛撤造成扬尘。施工垃圾及时清运，清运
时，适量洒水减少扬尘。
（2）施工道路采用硬化，并随时清扫洒水，减少道路扬尘。
（3）工地上使用的各类柴油、汽油机械执行相关污染物排放标准，不使用气体排放超标的机
械。
（4）搅拌站设置封闭的搅拌棚，在搅拌机上设置喷淋装置。
8.3防止施工噪声污染措施
（1）作业时尽量控制噪音影响，对噪声过大的设备尽可能不用或少用。在施工中采取防护等

措施，把噪音降低到最低限度。
（2）对强噪声机械(如搅拌机、电锯、电刨、砂轮机等)设置封闭的操作棚，以减少噪声扩散。 （3）在施工现场倡导文明施工，尽量减少人为的大声喧哗，不使用高音喇叭或怪音喇叭，增
强全体施工人员防噪声扰民的自觉意识。
（4）尽量避免夜间施工，确有必要时及时向环保部门办理夜间施工许可证，并向周边居民告
示。
