摘要
文章根据隧洞的特点、承担任务和所处地质条件,结合陕西省某实际工程,分析了引起隧洞塌方的原因,从先排水、短进尺、弱爆破、早支护、快封闭、勤量测七个方面介绍了预防坍塌的施工措施,希望通过实践能证明此法则对于预防不良地质段预防坍塌是一种有效的措施。
院 Basing on the tunnel characters、tasks undertake %the geological conditions and some real projects. This paper analyst the causes of collapse, from drainage、 pipe ahead 、 short footage、weak explosion、 early support、 fast closing and diligence measure,the seven aspectsIntro- duces preventing measures, which be used in practice to prove this measures are effective to prevent the collapse of adverse geological sec- tions.
