2007年10月2日,某市穿越江底隧道的旁通道,发生大量流砂涌入,引起隧道受损及周边地区地面沉降,造成三幢建筑物严重倾斜及部分防汛墙沉陷,造成直接经济损失1.6亿元。因事故处理及时,未造成人员伤亡。该工程建设单位为某市地铁建设有限公司,施工总承包单位为某市隧道工程股份有限公司(以下简称隧道公司);隧道公司将该部分工程中的隧道中间风井、旋喷加固、旁通道、垂直通道、冻结加固及风道结构工程专业分包给某矿山工程公司;某市地铁监理公司负责监理。
经调查,造成事故的原因是分包商——某矿山工程公司指定的“冻结法施工方案调整”存在缺陷,施工过程中在旁通道冻结条件不太充分的情况下,进行开挖;地铁监理公司现场监理人员失职,发生事故时,现场没有监理人员;分包项目存在漏洞,总包单位也未就施工方案向分包公司做说明,隧道公司质量安全员一次也没有去施工作业面进行技术、质量检查。
