(一)施工单位应对施工人员进行技术、质量、安全的交底,对有关施工作业人员进行法制教育(如《建筑法》、《刑法》等)以及安全生产教育。严格按基坑结构支护设计要求及有关国家、行业、地方的技术标准、规范、规程进行施工,实行技术交底、自检、工序交接、工程隐蔽验收等制度,使工程质量和安全得以控制。
(二)基础施工应具备下列资料:
(1)施工区域内建筑基地的工程地质勘察报告。勘察报告中,要有土壤的常规物理力学指标,必须提供土的固结块剪内摩擦角ψ、内聚力c,渗透系数K等数据和有关建议。
(2)暗挖施工图。
(3)场地内和邻近地区地下管线图和有关资料,如位置、深度、直径、构造及埋设年份等。
(4)邻近的原有建筑、构筑物的结构、基础情况,如有裂缝、倾斜等情况,需作标记、拍片或绘图,形成原始资料文件。
(5)基础施工组织设计。
(三)施工方案:
暗挖专项施工组织设计(方案),对施工准备、暗挖方法、初支、施工抢险应急措施等根据有关的规范要求进行设计、计算。施工方案要经过主管领导及有关部门批准后方可实施作业。作业前,要对作业人员进行三级安全教育及具有针对性的安全技术交底。
(四)土方开挖:
机械开挖时,严格按照土石方施工中的技术规程要求去做。挖掘土方应由上而下进行,不可掏空底脚,不得上下同时开挖,也不得上挖下运,如果必须上下层同时开挖,一定要岔开进行。挖土分层计划,高差,软土地区的基坑开挖,基坑内土面高度应保持均匀,高差不应超过1m。
(五)坑边荷载及上下通道:
坑边一般不宜堆放重物,如坑边确须堆放重物,边坡坡度和板桩墙的设计须考虑其影响;基坑开挖后,坑边的施工荷载严禁超过设计规定的荷载值。坑边堆土、料具堆放及机械设备距坑边距离应根据土质情况、基坑深度进行计算确定。作业人员上下应搭设稳固安全的阶梯。挖土的土方不得堆置在基坑附近,应离基坑1.5m以上,高度1.5m。机械挖土时必须有足够措施确保基坑内的桩体不受损坏。
(六)暗挖施工时,由于降水,土方开挖等因素,影响邻近建筑物、构筑物和管线的使用安全时,应事先采取有效措施,如加固、改迁等,特别是各种压力管道要有防裂措施,以确保安全。

深度超过2m的基础施工要根据《建筑施工高处作业安全技术规范》(JGJ80—91)的要求在基坑周围设置符合要求的防护栏杆,防护栏杆侧用密目式安全网封闭;无法放坡的基坑按照施工方案进行支护。防护及支护设施完成后要及时进行验收。施工过程中如果支护设施产生变形、位移,必须立即采取措施进行调整或加固。
(八)作业环境:
暗挖施工属于危险作业场所,要对施工现场设施及周边环境做好变形监测。监测要做好记录,主要是对支护设施、周边已有建筑物、构筑物、重要管线和道路的沉降、位移、变形情况及时掌握。当发生异常时,及时采取有效可靠的措施,防止事故的发生。坑内人员不得在未加固处理的坑壁下方操作、走动、停留,要离开坑壁一定的距离。操作时应随时注意上方土质的变化情况,发现问题时,作业人员要迅速撤离并及时加固处理。夜间施工要尽量安排在地形平坦、施工干扰较少和运输道路畅通的地段,并备足够的照明和警示灯。
(九)严禁在危险地段搭建临时建筑物。
