Embodiment Construction

[0016] The SVA numerical simulation method of the complex seepage control structure seepage problem provided by the present invention comprises the following steps:

[0017] (1) The complex seepage control structure is simulated by the drainage substructure method, and the finite element model is constructed with coarse mesh elements;

[0018] (2) The potential overflow boundary and the engineering seepage control structure boundary are expressed as Signorini complementary conditions, and the variational inequality method is used to solve the problem of precise location of the boundary seepage overflow point;

[0019] (3) The problem of precise positioning of the seepage free surface of the complex seepage control structure is solved by using the self-adaptive penalty Heaviside function.

[0020] The above-mentioned seepage control structure at least includes drainage holes, drainage wells, pumping wells, drainage holes and drainage corridors, and its boundary conditions can b...

Abstract

This invention relates to one complex mixture control structure flow SVA value analogue method, which comprises the following steps: simulating the complex mixture control structure by drainage structure and adopting rough network unit to form limit element module; describing the latent overflow boundary and engine mixture control structure boundary as Signorrini compensation condition to solve boundary overflow point accurately positioning problem; by self-adapting penal Heaviside function to solve the position problem of the overflow free page.

Description

technical field [0001] The invention relates to a substructure-variational inequality-adaptive (referred to as substructure-variational inequality-adaptive method) for the seepage problem of complex seepage control structures including a large number of drainage holes, drainage wells, pumping wells, drainage tunnels and drainage corridors in water conservancy and hydropower projects and geotechnical engineering SVA) numerical simulation method. Background technique [0002] In dams, dam foundations, slopes, underground powerhouses and other projects in water conservancy and hydropower projects, the seepage and control of groundwater are generally involved. The complexity of this type of problem comes from the following three aspects: First, the complexity of the medium, that is, the problem involves a variety of media with greatly different permeability characteristics, such as anti-seepage curtains, concrete, strong permeable rock formations, weak permeable rock formations ...
