Abstract

The invention relates to an optimal design method of a freezing method under a seepage condition based on an ant colony algorithm. The optimal design method comprises the following steps: determiningthe number of freezing pipes, the radius of the freezing pipes, the construction tunnel type, the freezing liquid type, land parameters and underground water conditions; determining an arrangement equation of the freezing pipe under the seepage condition according to the data; establishing a thermal-water coupling finite element model according to the arrangement equation of the freezing pipes incombination with given boundary conditions and initial conditions; and constructing a mapping relationship between the freezing pipe optimal arrangement problem under the seepage condition and the antcolony algorithm by applying the ant colony optimization algorithm in combination with the thermal-water coupling finite element model, so as to obtain freezing pipe arrangement optimization resultsunder different seepage conditions. Compared with the prior art, the method has the advantages that the ant colony algorithm and the finite element model are combined, the freezing pipe arrangement optimization design in the presence of seepage is quickly and efficiently obtained, and the freezing curtain which is regular in shape and meets the quality required by engineering is formed under the condition that the number of the freezing pipes is not increased and the time is minimum.

Description

technical field [0001] The invention relates to the field of freezing method construction, in particular to an optimal design method of freezing method under seepage condition based on ant colony algorithm. Background technique [0002] In the process of underground engineering construction in soft ground with high groundwater level or other soils with poor engineering geological conditions, the artificial freezing method has gradually become the most important method in underground engineering excavation due to its advantages of reversibility, environmental protection, and wide application range. The most commonly used construction method. The uniform arrangement of freezing tubes is a more commonly used arrangement in engineering practice. However, during the freezing process, due to the existence of underground seepage, the freezing curtain formed around the uniformly arranged freezing pipes often has different thicknesses, and the required freezing time is longer. In s...
