Abstract

The invention discloses a subsea tunnel active control mode waterproof and drainage system design method and system; the method comprises the following steps: obtaining subsea tunnel engineering parameters and subsea tunnel allowance displacement; determining a tunnel surrounding rock original seepage according to the subsea tunnel engineering parameters; determining whether or not the tunnel surrounding rock original seepage is bigger than the subsea tunnel allowance displacement; if yes, obtaining tunnel structure seepages corresponding to employed different waterproof and drainage measures,and calculating water loads that are held by different waterproof and drainage measures; if not, determining the active control mode waterproof and drainage system according to the tunnel structure seepages and the water loads. The design method and system can reduce the subsea tunnel waterproof and drainage design subjectivity and scientific values, can prevent wastes, and can remove tunnel construction safety troubles caused by unreasonable designs.

Description

technical field [0001] The invention relates to the field of subsea tunnel drainage, in particular to a design method and system for an actively controlled waterproof and drainage system of a subsea tunnel. Background technique [0002] The subsea tunnel is buried under the seabed, and there is an unlimited water source to supply it. Due to the limitation of the V-shaped longitudinal slope, natural drainage cannot be achieved, and artificial drainage can only be used. However, the subsea tunnel bears a large water head and acts on the supporting structure. Therefore, the rationality of the waterproof and drainage design determines the safety of the support structure and the drainage cost during operation. [0003] In tunnel projects at home and abroad, the commonly used waterproof and drainage methods can be divided into two types: fully enclosed type and drainage type. With a fully enclosed waterproof tunnel, the support structure has to bear the external water pressure th...
