Embodiment Construction
[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0038] The present invention provides a method for early warning and prevention of water inrush in rich water tunnels under the influence of fault fracture zone, which is specifically implemented according to the following steps,
[0039] Step 1: Based on the engineering investigation data, including: engineering geology, hydrogeology, construction logs and inspection information of the test section, systematically analyze the hazard characteristics of water inrush in the tunnel engineering background under study, and obtain the influencing factors that induce water inrush: bad Geology, stratum lithology, soluble rock and non-soluble rock contact zone, rock integrity coefficient and Poisson's ratio, topography, rock formation (dip angle of ), interlayer fissures, surrounding rock grade, rainfall, surrounding rock stress (lateral pressure coe...

The invention discloses an early-warning prevention and control method for water inrush of a water-rich tunnel under the influence of a fault fracture zone. The method is specifically implemented according to the following steps: 1, acquiring impact factors for inducing water inrush; 2, determining qualitative indexes and quantitative indexes of all the impact factors of water inrush; 3, determining a water inrush forecasting level according to the probability of water inrush of the tunnel; 4, constructing a membership function of each impact factor of water inrush and each evaluation index weight so as to obtain the level of possible water inrush of the tunnel ; 5, compiling the early-warning process of water inrush into a visual analysis platform; 6, acquiring a water inrush level; 7, acquiring a comprehensive scheme capable of ensuring the stability of surrounding rock and reducing gushing water; and 8, establishing a early warning and treatment measure comprehensive analysis platform for water inrush. According to the method, early warning and treatment measures of water inrush existing in the water-rich highway tunnel in the fault fracture zone are optimized.
Description
technical field [0001] The invention belongs to the technical field of geotechnical engineering information construction, and in particular relates to a method for early warning and prevention of water inrush in rich water tunnels under the influence of fault fracture zones. Background technique [0002] In recent years, due to the sudden increase in demand for transportation and infrastructure, especially the large-scale construction of expressways and railways, most projects need to be constructed in the form of tunnels through mountains. The safety of the tunnels during the construction period is the key to the success of the project. The steep mountains, poor strata lithology, wide distribution of soluble salts, high groundwater level, and greater impact of rainfall, during the construction of the tunnel, the surface runoff is likely to be mixed with the groundwater in the stratum where the tunnel is located and the fissure water in the fault fracture zone. Connected, th...
