Abstract EN

Compared with ordinary tunnels, the influence analysis of underwater tunnel adjacent constructions is more complicated.

At present, the empirical method used to divide the influence zone of the tunnel adjacent constructions has great uncertainty.

So it is of great significance for actual construction and design to determine the influence zone accurately according to theoretical calculations.

In this paper, based on the Hoek–Brown nonlinear failure criterion of rock mass and taking seepage factor into account, the stress state of rock mass around the underwater tunnel adjacent constructions can be deduced by elastoplastic theory.

Then combined with the concept of “loose zone-bearing zone”, the influence zone division method of underwater tunnel adjacent constructions is proposed, and it is applied to the analysis of engineering examples.

Through the deduced theoretical formulas, the influence zone of underwater tunnel adjacent construction can be divided into extensively strong, strong, relatively strong, weak, and noninfluence zones.

Corresponding the influence zones with the risk levels in the code, different control measures are adopted for different risk levels, which can provide certain guidance for the design and construction of tunnel in practical engineering.
