Problems solved by technology

Now, there are few systematic and scientific proposals that do not deal with expansive soil in seasonally frozen soil regions, but allow expansive soil to have a certain lateral deformation and do not bring structures such as extra force or displacement. The method of structural damage or unreasonable adverse effects of design is mainly to control the water content of expansive soil, improve the soil properties of expansive soil, release the expansion potential in advance, and reinforce in expansive soil. The treatment measures are not based on the idea of ​​allowing the expansive soil to deform to reduce the expansion force, which makes many expansive soil treatments in engineering will cause economic waste
In addition, in the existing technologies, there are few methods of actively controlling the expansion and lateral displacement of expansive soil in seasonally frozen soil regions through intelligent control technology. Technology rarely uses green energy to reduce damage to the environment

Abstract

The invention discloses an intelligent supporting structure of expansive soil in a seasonally frozen region. The intelligent supporting structure comprises a steel plate pile-inner support supporting system, main control components and a wind-light complementation energy supply system. The invention provides an effective method for economically and reasonably controlling expansion lateral sway of the expansive soil in the seasonally frozen region. An intelligent control technology is introduced for the main control components, the expansive soil in the seasonally frozen region is allowed to generate certain lateral sway (expansion or contraction), the adverse effects that structure damage or uneconomical design and the like are generated due to generated extra force or displacement are prevented from being brought to the structure, meanwhile, the supporting performance of the whole supporting system is not influenced, the supporting structure can be designed according to non-expansive soil, and the expansive soil in the seasonally frozen region does not need to be treated. By means of the complementation energy supply system of a wind-light power generation manner and a photovoltaic power generation manner, green energy can be acquired from different weather conditions and even the severe environment to be supplied to an intelligent control system to be used, and it is guaranteed that the whole intelligent control system ceaselessly and normally works for a long time.

Description

technical field [0001] The invention belongs to the technical field of environmental geotechnical engineering, and relates to an intelligent retaining structure of expansive soil in seasonally frozen soil regions. Background technique [0002] The characteristics of expansive soil, such as water absorption, expansion and loss of water shrinkage, will bring many problems such as ground uplift and subsidence, uneven settlement and cracking of buildings, deformation and creep of slopes, damage and cracking of retaining walls and basements, and deformation of underground pipelines. , damage and other engineering damage. In the seasonally frozen soil area, there are also effects of soil frost heaving and thawing. In order to cope with the adverse effects of expansive soil in seasonally frozen soil regions, physical methods, chemical methods, and biological methods are usually used in engineering to strengthen expansive soil, that is, to suppress the deformation of expansive soil...
