Problems solved by technology

The main problems faced by the frame tunnel structure in service are tunnel water leakage, structural cracks and longitudinal uneven settlement, which even pose a threat to the safe operation of underground transportation in some sections
[0003] The disease status of the tunnel structure can be obtained through the disease investigation, but there is no clear classification standard for the disease level at present, and it is impossible to determine the safety status of the tunnel structure based on the existing data, especially for the specific structural form and disease characteristics of the frame tunnel

Embodiment

[0027] Such as figure 1 As shown, a safety status evaluation and maintenance method for an underground frame tunnel structure can be simply and conveniently judged based on actual damage conditions by reasonably grading the safety status of the frame tunnel structure, so as to take reasonable maintenance measures in a timely manner Provide basis and guarantee.

[0028] This method classifies and defines the structural safety status according to the three levels of structural components, structural sections, and the overall structure, and gives corresponding suggestions for maintenance measures. Specifically include the following steps:

[0029] S1, divide the tunnel into multiple structural sections;

[0030] S2. According to the division standard of this step, evaluate the safety status of the structural components of each structural section, specifically: evaluate the hazard levels of water leakage, tunnel cracks, and tunnel uneven settlement deformation according to their...

Abstract

The invention relates to an underground framework tunnel structure safety state evaluation and maintenance method. The underground framework tunnel structure safety state evaluation and maintenance method includes the following steps that S1, a tunnel is divided into multiple structural sections; S2, level assessment is conducted on structure component safety states of the structural sections; S3, the safety states of the structural sections are divided into multiple levels from high to low, and level assessment is conducted on the safety states of the structural sections according to classification standards; S4, the overall structure safety states are divided into multiple levels from high to low, and level assessment is conducted on the overall structure safety states according to the classification standards; S5, corresponding maintenance measures are adopted for maintenance according to level assessment results of the overall structure safety states of the tunnel. Compared with the prior art, the method describes the current state of the tunnel structure reasonably, refers to existing specifications and combines with the actual disease investigating and survey situation and has the advantages of good practicability, distinct gradation and the like.

Description

technical field [0001] The invention relates to a method for evaluating the safety state of a building, in particular to a method for evaluating and maintaining the safety state of an underground frame tunnel structure. Background technique [0002] With the massive construction and long-term operation and use of urban underground space projects, the problem of tunnel structure diseases has become increasingly prominent. The main problems faced by the frame tunnel structure in service are tunnel water leakage, structural cracks and longitudinal uneven settlement, which even pose a threat to the safe operation of underground transportation in some sections. [0003] The disease status of the tunnel structure can be obtained through the disease investigation, but there is no clear classification standard for the disease level at present, and the safety status of the tunnel structure cannot be determined based on the existing data, especially for the specific structural form an...
