1.The uniqueness theorem of generalized quasi-analyticity of the infinitely differentiable functions in some closed angular domain is extehded to the functions of several complex variables.
3.However, the settlement curves of these two typical continuous beam models (Timoshenko and Euler-Bernoulli) are smooth and differentiable, failing to describe the discontinuous features of shield tunnel settlement.
4.The settlement curve computed by the proposed method is neither smooth nor differentiable when subjected to the ground surface surcharge, compared with LECM, which is closer to the characteristics of real tunnel settlement.
