GUIDELINES FOR AVOIDING TUNNEL COLLAPSES
The causes of tunnel collapses during construction and repair methods are considered. Such failures are rather infrequent as demonstrated by the authors' own experience of 30 years and 1000km of tunnels and as noted by other experts in the tunnelling profession. Normally, the large industrial activity of tunnelling is invisible, comparatively less noisy and less dangerous than surface construction, and generally devoid of fatalities, even in the case of collapses. The rare occurrence of a collapse that reaches the surface in an urban area makes headlines in the media and is a negative advertisement for the profession. Of course, there are inordinate costs and schedule delays associated with significant tunnel collapses. Regardless of who pays for the consequences of the collapses, the ultimate burden is transferred to the profession and, finally, to the citizens or taxpayers. In any case, it is important to know what causes the collapses and how they are repaired. In addition to answering these questions with the help of some examples, authors will also attempt to answer the contentious question- are tunnel collapses unavoidable? The authors are aware of, and acknowledge, a large number of coordinated studies and initiatives to resolve the above questions.
