【摘要】 雪峰山隧道为深埋特长隧道。在该隧道的勘察过程中运用了大量高新技术,并开展了科研工作,对隧道围岩特性、地质构造、地应力场及岩爆、涌水量、围岩稳定性等与隧道设计、施工密切相关的问题均作出了准确的判断和预测。本文论述了一些新的勘察技术及科研成果,这些勘探与评价技术对其它深埋特长隧道有较好的借鉴作用。更多还原

【Abstract】 The Xuefeng mountain tunnel is a deep imbedded and extra-long tunnel.By making use of high technology means and developed scientific research,we have fond out conditions of the surrounding rock,the geological structure characters,the geostress field,correctly assessed on main engineering geological problems,for example,rockburst,water outflow and surrounding rock stability.This paper introduct some new exploring techniques and scientific reseach achievements.These techniques and scientific research achievement will be useful reference to the exploring of the other long tunnels.更多还原
