Abstract
The invention belongs to the technical field of utility tunnels, and provides an underground utility tunnel anti-floating structure and an anti-floating checking computation method thereof. The underground utility tunnel anti-floating structure comprises a utility tunnel box-shaped main body and jointing plates, wherein the utility tunnel box-shaped main body is arranged in an underground rock-soil body, and the jointing plates with equal or unequal lengths are arranged on the two sides of a bottom plate of the utility tunnel box-shaped main body. The utility tunnel box-shaped main body and the jointing plates are both of reinforced concrete structures, and the jointing plates and the bottom plate of the utility tunnel box-shaped main body are poured synchronously, and the jointing plates and the bottom plate of the utility tunnel box-shaped main body are of an integrated structure. According to the underground utility tunnel anti-floating structure, the jointing plates are arranged on the two sides of the bottom plate of the utility tunnel box-shaped main body, so that self-weight of the soil body above the jointing plates can be utilized to resist water buoyancy, compared with traditional anti-floating methods of adopting bored piles and anchor rods, the underground utility tunnel anti-floating structure has better economy and construction convenience and is stable and reliable, and the anti-floating problem of an underground utility tunnel is effectively solved; and in addition, the anti-floating checking computation method comprises integral anti-floating stability checking computation and further comprises longitudinal and transverse local anti-floating stability checking computation, and can be used for guiding engineering design.
Description
technical field [0001] The invention belongs to the technical field of comprehensive utility tunnels, and in particular relates to an anti-floating structure of an underground comprehensive utility tunnel and an anti-floating checking calculation method thereof. Background technique [0002] The comprehensive pipe gallery is a structure built underground in the city to accommodate various municipal pipelines. The cross-section of the comprehensive pipe gallery is small in size, long in length, and high in overall cost. When the groundwater level is high, the integrated pipe gallery needs to consider the problem of anti-floating, and its anti-floating safety factor must meet the requirements of national regulations. Although the longitudinal section of the standard section of the pipe gallery can generally resist buoyancy through the self-weight of the rock and soil on the top of the pipe gallery, most of the nodes, such as hoisting openings, ventilation openings, branch ope...
