Embodiment Construction

[0037] combine figure 1 The method of the present invention is described as follows:

[0038] (1) Establish a tunnel construction safety evaluation index system;

[0039] (2) Establish a judgment matrix;

[0040] (3) Judgment matrix consistency check, if the consistency is not satisfied, then return to the previous step; if the consistency is satisfied, then enter the next step;

[0041] (4) Calculate the weight coefficient;

[0042] (5) Evaluate the safety status of tunnel construction in combination with multi-information early warning system.

[0043] The specific steps are:

[0044] (1) Establish an evaluation index system for tunnel construction risk

[0045] According to the main factors collected in the tunnel construction multi-information early warning system, 8 single factors are determined, and the safety evaluation of the tunnel construction status is carried out in three levels. The main factors are divided into three items: human factors C 1 , equipment fa...

Abstract

The invention discloses a tunnel construction process safety evaluation method based on a multi-element information early warning system. The tunnel construction process safety evaluation method comprises the following steps: (1) establishing a tunnel construction process safety evaluation index system; (2) establishing a judging matrix; (3) judging matrix consistency checking; if the consistency is not met, returning back to the last step; if the consistency is met, entering the next step; (4) calculating a weight coefficient; (5) evaluating a tunnel construction safety state by combining the multi-element information early warning system. By adopting the tunnel construction process safety evaluation method, the technical problems of a traditional evaluation method that great manual subjective factor influence and certain boundedness exist, many indexes cannot be comprehensively considered scientific analysis and processing cannot be carried out, and the like can be solved.

Description

technical field [0001] The invention relates to a safety evaluation method for tunnel construction, in particular to a safety evaluation method using a multi-information early warning system during tunnel construction. Background technique [0002] Due to the diversity and complexity of the geological conditions of the surrounding rock of the tunnel, the incidence of construction accidents is higher and more serious than other geotechnical projects, and it is prone to mass death and mass injury accidents, which brings serious physical and mental harm to the tunnel construction workers and has a bad social impact. . Therefore, the safety of tunnel construction has always been the focus of attention, and ensuring the safety of tunnel construction is an important issue that urgently needs to be studied and solved. [0003] At present, the safety evaluation methods often used in the field of transportation construction projects in my country are mainly qualitative safety evalua...
