Early warning treatment and detection process for underground structure differential settlement diseases

Abstract

The invention discloses an early warning treatment and detection process for underground structure differential settlement diseases, and belongs to the technical field of underground structure disease treatment, the early warning treatment and detection process comprises the following steps: monitoring differential settlement displacement values at two sides of a disease part, and drawing a monitoring process curve; curve fitting is carried out, and an optimal fitting curve and an optimal fitting function expression are determined through comparison and selection; comparing a non-uniform settlement displacement monitoring value corresponding to a monitoring ending moment, a non-uniform settlement displacement predicted value corresponding to a certain moment in the future and a non-uniform settlement displacement allowable value, and performing early warning evaluation on the disease degree of the part; treating the part needing to be repaired and treated by adopting a grouting lifting method or a compaction reinforcement method; and establishing a quantitative evaluation index of the disease repair treatment effect, and quantitatively evaluating the repair treatment effect. Quantitative evaluation of the safe operation and maintenance state of the repaired underground structure can be achieved, and the problem that an effective quantitative early warning and treatment detection technology is lacked for the differential settlement disease of the underground structure at present is solved.

Description

technical field [0001] The invention relates to the technical field of underground structure disease control, in particular to an early warning control and detection process for underground structure non-uniform settlement diseases. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] While the scale of infrastructure development such as urban ground buildings and transportation is growing day by day, a series of problems such as noise, congestion, and environmental pollution have emerged. Urban underground space is a precious resource in urban construction and development. Its development and utilization can provide new space for urban infrastructure and life services, and can effectively alleviate the above problems. At present, common urban underground space projects mainly include underground railways, underground tunnels, underground comprehensive...

Problems solved by technology

[0006] (1) At present, there is still a lack of a complete set of effective early warning detection technology and scientific evaluation methods to support it. It is difficult to carry out effective long-term real-time monitoring of potential non-uniform settlement diseases, and it is impossible to analyze the process of non-uniform settlement diseases based on real-time monitoring data. Real-time evaluation of evolution characteristics, and effective prediction of future development trends of non-uniform settlement diseases;

[0007] (2) At present, when using conventional technology to detect and evaluate non-uniform settlement diseases of underground structures, it is often only to compare the non-uniform settlement deformation value obtained at a certain moment with the allowable value to judge whether there is a disease problem, and not to consider the disease. Process evolution characteristics and future development trends, the detection and evaluation methods and evaluation index standards of non-uniform settlement diseases need further in-depth research and optimization;

[0008] (3) Regarding the treatment of non-uniform settlement diseases of underground structures, since the underground structure is buried underground, it is a concealed project, and the outer surface of the underground structure itself contains a waterproof layer. Internally deal with it, so the current technology and methods for the treatment of non-uniform settlement diseases of underground structures are still immature, which is also a technical problem that the industry needs to face at present;
