Problems solved by technology

The area where the rock is strongly broken by the fault is the fault fracture zone. Due to the low bearing capacity of the rock mass, poor overall stability, and the fact that the groundwater is easy to accumulate here, the tunnel passing through this area is prone to water gushing and mud outburst, which may cause landslides, etc. Accidents seriously threaten construction safety and affect construction progress

[0482] 1, tunnel surge water disaster information record

[0483] According to the evaluation index of the tunneling water disaster, the infrasound disaster information record form, such as 0. During the tunnel construction process, the technician can record the probability evaluation index information of the inlay water disaster in accordance with the inlay water disaster information.

Abstract

The invention relates to a fault fracture zone tunnel gushing water disaster occurrence probability grade evaluation method. The method comprises the steps of designing index system constituent elements; establishing a water inrush disaster occurrence probability evaluation index system; obtaining each level membership degree of the evaluation index of the occurrence probability of the water inrush disaster by utilizing an expert evaluation mechanism; carrying out weight calculation on the evaluation indexes of the occurrence probability of the water inrush disaster; and evaluating by adopting a multi-level fuzzy comprehensive evaluation method. The method overcomes the defect of subjectivity of a decision result of an analytic hierarchy process in existing disaster risk evaluation, adopts a fuzzy comprehensive evaluation method to make a decision, describes and quantifies fuzzy uncertainty factors by utilizing concepts of a fuzzy set and membership, weakens subjectivity of evaluation by adopting an entropy weight method, and the defect of relatively high uncertainty in evaluation of the occurrence probability grade of the water gushing disaster in the tunnel is overcome.

Description

Technical field [0001] The present invention relates to the exploitation of the probability level evaluation of tunneling water damage, and specifically, there is a probability of evaluation method for the occurrence of aqueous disaster in tomaton disaster tunnel tunnel. Background technique [0002] With the rapid development of China's transportation, the number and scale of tunnel engineering construction is increasing, and the tunnel projects of complex geological environments such as fault breakage belts are increasingly common. The strong crushing area caused by the fault is a fault breakage. Due to its low carrier capacity, the overall stability is poor, and the groundwater is easy to enrich, so the tunnel is prone to spring, and the mud, which causes landslide, etc. Incident, severe procrars construction safety, affect construction progress. For the evaluation of the probability level of tunnel water disasters, it is directly related to the results of risk disaster level,...
