Abstract

The invention discloses a tunnel engineering risk situation fuzzy evaluation method and system. The method comprises the following steps that according to a tunnel engineering practical building environment, based on building conditions, prospective design, construction technologies and operation management factors, tunnel engineering risk evaluation indexes are determined; a tunnel engineering risk evaluation index layer is established; the tunnel engineering risk evaluation index layer is combined, a tunnel engineering risk situation fuzzy evaluation hierarchical model is established; according to expert evaluation opinions, the weight of the tunnel engineering risk evaluation indexes in the index layer obtained after validity correction processing is determined; according to the expert evaluation opinions, a fuzzy evaluation matrix obtained after validity correction is established, and according to the fuzzy evaluation matrix, bottom index layer nodes belong to risk situation evaluation index evaluation sets on a criterion layer; and tunnel engineering risk situation indexes are computed. The risk situation of tunnel engineering is evaluated by introducing fuzzy mathematics and a fuzzy layering method, and accordingly the problems of data uncertainty in tunnel engineering risk situation evaluation and influence on evaluation results are solved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a method for fuzzy assessment of tunnel engineering risk situation. Background technique [0002] With the increasing complexity of the tunnel engineering construction environment, various risk events occur from time to time, causing great harm to the construction and use of tunnel engineering. Common tunnel engineering safety risk control measures, such as water and mud inrush risk control, explosion risk control, rockburst risk control, collapse risk control, etc., the tunnel risk information obtained can only be used for early warning and prevention of a single tunnel risk event, which is difficult to describe from The degree of risk during the entire construction period of the tunnel project from survey and design to construction and operation. The risk degree of tunnel engineering refers to the state and change process of the overall risk of tunnel engineer...
