摘要:Urban tunnel engineering has the characteristics including poor engineering geological condition, sensitive to displacement transformation of ground building structure, complicated underground pipeline network, complex construction managements, high degree of difficulties, and more potential risk factors, which are so easy to cause collapses, ground-surface settlements, cracks on upper building structure, and the collapse engineering accidents so that it a risk management analysis. By building the urban tunnel construction mechanical model and designing the orthogonal simulating test scheme, the ground settlement value of tunnel construction is calculated by using the orthogonal simulating test hierarchy theory, the influence weight of complex risk index at every factor level in tunnel construction is calculated. The tunnel construction risk value and the risk ranking of each working condition combined with Jiaozhou Bay sub-sea tunnel are obtained.
