【摘要】 在隧洞施工中,影响施工的关键因素是塌方、涌水、突水造成停工事故,只要能进行准确超前预报,把事故消灭在开挖之前,就可以加快施工进度,降低工程造价。因此,地质预报工作是十分重要的,而且是提高施工速度的重要措施之一。更多还原

【Abstract】 In the construction of tunnel,the key factors affecting the construction are collapse,inrush of water;gushing water,sudden that give rise to stoppage of work.It can quicken the construction progress and abate the project cost so long as accurate advance forecast and elimination of accidents before excavation.Thus the geological forecast is not only of great significance,but one of important measures to boost construction speed.更多还原
