The research results of regional hydrogeology, engineering geological division and its related parameters are collected and analyzed. The characteristics of major faults, rock veins and fracture groups are grasped, especially the fault permeability and connected extension characteristics, the zone and permeability of joint fracture development are paid attention to, and the water transportation system is collected and analyzed. The location and scope of grouting reinforcement and plugging extension at different stages of the area are also discussed.
2) analysis of the coupling effect of the region flow and heat in the water conveyance system
On the basis of relevant documents, a group of three full coupling equations of transient flow, solid and heat are set up on the basis of the relevant literature. (including three coupled processes of solid deformation, energy transfer and fluid flow, the cross coupling between the multi physical fields also includes the properties of material and the only one. " The coupling relationship between independent variables), and then using the COMSOL software (the multi physical process simulation tool based on partial differential equations) as a platform, the whole coupling partial differential equation group is successfully solved, and the regional flow and solid heat coupling field of the water transmission system of the Tian Huang Ping pumped storage power station is obtained.
3) use geo radar to detect concentrated leakage area in water conveyance system area.
On the basis of the geological survey data of the East China Hospital and the detection data of the weak leakage parts of the Hohai University, the geological radar detection means are used to set up the test points in the seepage point of the tunnel wall, such as the holes and the construction branches. The water rich fault and the joint zone in the water transportation system are detected, and the shallow seepage passage of the seepage points of each tunnel wall is preliminarily determined, and the next one is the next one. The basis is provided for the inversion analysis of the step concentrated leakage channel.
4) hydraulic fracturing analysis of surrounding rock of water conveyance tunnel under high head action
In view of the shortage of hydraulic fracturing analysis, the following problems are studied in accordance with the principle of fracture mechanics: (1) the calculation method of type I stress intensity factor of various types of cracks in the surrounding rock of underground caverns, the theoretical criterion of hydraulic splitting of composite type cracks, and the mechanical mechanics of compressive shear fracture, and the strength of pressure shear fracture stress with water pressure The above theory is applied to the hydraulic fracturing analysis of the surrounding rock in the bifurcated area of the water conveyance system of the Tian Huang Ping pumped storage power station.
