Abstract

The invention discloses a karst tunnel water inrush level evaluation method based on a trapezoidal cloud model under a one-dimensional X condition. The method comprises a step of constructing an evaluation indicator system for a karst tunnel water inrush risk level, classifying water inrush risk and determining a level division standard, and carrying out quantification processing on a non-quantitative indicator at the same time, a step of calculating the numerical characteristics of the trapezoidal cloud model under different risk indicators and thus completing the construction of the trapezoidal cloud model, a step of referring to and analyzing previous cases of karst tunnel construction and completing the establishment of a risk indicator system weight vector by using an analytic hierarchy process, a step of carrying out field survey and measurement to obtain risk indicator observation and measurement data and introducing the risk indicator data by using a cloud model algorithm underthe one-dimensional X condition to obtain different risk level membership degree values corresponding to indicators to complete the construction of a fuzzy comprehensive evaluation matrix, and a stepof selecting a suitable fuzzy synthetic operator and fusing the weight vector and the fuzzy comprehensive evaluation matrix to obtain a water inrush risk grade membership degree vector and determining the karst tunnel water inrush risk level.

Description

technical field [0001] The invention relates to a method for determining the water inrush risk of a karst tunnel based on a trapezoidal cloud model under a one-dimensional X condition. Background technique [0002] Water inrush is a common geological disaster in tunnel engineering construction. It is difficult to control the inrush of groundwater in the surrounding rock aquifer under the combined action of head pressure and other pressures to overcome barriers such as aquifers and fissures during tunnel construction. disaster risk. The occurrence of water inrush disasters has seriously threatened the quality of the project and the safety of construction personnel and equipment. Serious water inrush accidents may destroy the entire tunnel project. In view of the above reasons, effective control of tunnel water inrush disasters plays an extremely important role in tunnel construction safety and engineering quality. [0003] In recent years, a lot of research has been done on...
