Risk Analysis during Departure and Reception of Shield in the Yellow River Crossing Tunnel of the Middle Route Project of South-to-North Water Diversion
In the Yellow River crossing tunnel of the middle route project of South-to-North water diversion, its geological conditions are very complicated, so potential risks are much likely to occur in the construction. Based on the fault tree analysis, fuzzy comprehensive evaluation method is also used for the quantitative analysis on the risks during the departure and reception phase of the tunnel construction. And it turns out that, there are risks of collapse of working well, leakage and plasma leakage, mechanical equipment failure and large deviation from the designed axis during the construction. Finally, the measures available of risk aversion are put forward, which have achieved good field applications and also provided some reference value for similar projects in the future construction.
