Technical Field
The invention relates to the field of geotechnical engineering, in particular to an anti-floating
simulation device of subways in karst areas.
Background Art
In recent years, the atmospheric greenhouse effect has led to climate warming, and coupled
with factors such as the aquifer structure and lithology of underground water, the underground
water level rises, threatening the structural safety of underground buildings. Therefore, the
research on the buoyancy of underground structures has become an extremely critical topic in
urban geotechnical engineering, which not only involves the changing trend of the underground
water level in the medium and long term development of a city, but also involves the pore water
pressure transfer mechanism and distribution law in soil layers with different underground water
occurrence modes, the buoyancy values of the underground structures located in different soil
layers, the buoyancy values during the action of multilayer underground water, the development
of reasonable engineering anti-floating measures and other problems.
With the continuous expansion of urban underground rail transit construction scale, most
subway stations are mainly constructed by shallow bury and open-cut construction. However, the
shallow underground water level of the city is relatively high, and the overall trend is unstable, so
that the subway safety plays an important role in the safety of the city, and then the anti-floating
design of the subway stations is a key link. A karst area has its special geological environment,
subway construction is often accompanied by natural phenomena such as karst caves and
subterranean rivers, the exploration of the anti-floating relationship of the subway stations in the
karst area must rely on a corresponding simulation device, therefore, a reasonable underground
anti-floating simulation device is designed to provide a data support for the anti-floating measures
of the karst area, which has become a hot research hotspot in the design of subway anti-floating.
Researches find that the current subway anti-floating simulation devices have the following
shortcomings: (1) from the functional point of view, most of the existing simulation devices are
one-sided for aeration zones or aquifers with general conditions, and lack organic combination
devices having the simulation functions of subterranean rivers and karst caves, thereby lacking the
underground anti-floating simulation function of karst areas; (2) the existing simulation devices
cannot easily change the simulated geological conditions, and the simulation accuracy of complex geological environments is not high; and (3) the design of the existing constant water head device is high in water fluctuation and is unstable, thereby having greater impact on later data.
These shortcomings have seriously affected the underground anti-floating design during the
subway construction in the karst areas. Facing the complex hydrogeological conditions of the
subterranean river system, underground anti-floating simulation in the karst areas has become an
important scientific research direction for scientists.
