一、序言长大隧道工程建设过程的成败之关键,是对隧道所处的地质条件是否清楚和能否采取与该地质条件相适应的施工方法,“地质明”是关键之关键。隧道建设前期的地质勘察工作,从广义上说,是对隧道地质条件的预测。它从整体上对隧道地质条件作出概略的评估,为技术设计、施工设计提供资料。可以说,它是属于远期预报。众所周知,期望在勘测设计阶段,将所有地质问题弄清楚是极其困难的,特别是水底隧
I. Preface The key to the success or failure of the project of tunnel construction is whether the geological conditions in the tunnel are clear and whether construction methods suitable for the geological conditions can be adopted. The key point of “geologic development” is the key. Geological prospecting in the early stage of tunnel construction, in a broad sense, is a prediction of tunnel geological conditions. It provides a rough assessment of the geological conditions of the tunnel as a whole, providing information for technical design and construction design. It can be said that it is a forward forecast. It is well known that it is extremely difficult to expect to find out all the geological issues during the survey and design phase. In particular,
