TL;DR: In this paper, a conformal mapping of the complex variable methods is derived for two-dimensional, steady ground water flow into a horizontal tunnel in a fully saturated, homogeneous, isotropic, and semi-infinite aquifer.

TL;DR: In this paper, a controlled drainage scheme is proposed for tunnels under high water level, for which there is no code provision for tunnel design and a suitable structure form is suggested and the distribution of water pressure on tunnel lining is studied by theoretical analysis.

TL;DR: In this article, a testing method of water pressure distribution law of a subsea tunnel lining is presented, and the method comprises the following steps: selecting similar materials to simulate a prototype tunnel surrounding rock mass and lining materials based on similarity theory, determining the shape of a testing template according to shape of the cross section of the water pressure-resistant lining, and completing the making of a model; arranging measuring points of the model, adopting a fiber Bragg grating to collect strain data of the structure, and adopting a U-shaped mercury manometer to carry out data acquisition of

TL;DR: In this paper, a 1:10 geo-mechanical physical model test was performed to understand the mechanism of pre-cutting method by simulating its construction process and the ground settlement, earth pressure and pre-arching stress during tunnelling were investigated.

TL;DR: In this article, a trough pre-cutting test model machine for tunnel construction is presented, where linear guide rails and an electric push rod form a body advancing drive structure which can accurately control the advancing speed and distance, so that the problems of inertial error, low shakeproof performance and complex control are avoided.
