Method for simulating construction course and tunnel deformation influence value of multiline overlapping tunnel

The invention belongs to the field of tunnel engineering and particularly relates to a method for simulating the construction course and a tunnel deformation influence value of a multiline overlapping tunnel. The method provided by the invention comprises the following operation steps: (1) determining a soil constitutive model; (2) simulating an initial dead-weight stress field; (3) simulating anequivalent layer structure; (4) simulating a tunnel duct piece structure; (5) simulating a slurry hardening course; and (6) simulating the influence course of shield propelling on subway tunnel operation. In the method provided by the invention, the complicated working conditions of multiline overlapping tunnel construction are considered in detail; a rigidness migration method is used for simulating a shield propelling course, wherein a life and death unit is preset in a lining and soil disturbance zone; and the dynamic course of shield construction is reflected by a method for activating the life and death unit to change the mechanics characteristics of the unit material in different construction steps. In the simulation method provided by the invention, a thin film unit is used for simulating the oblique crossing construction working conditions of the multiline overlapping tunnel at any angle; and the defect that a conventional finite element method is difficult to converge when the construction working conditions are simulated can be avoided.

Method for determining safe distance between concealed karst cave and newly built mountain tunnel

The invention belongs to the field of tunnel engineering, and particularly relates to a method for determining the safe distance between a concealed karst cave and a newly built mountain tunnel. According to the method, ANSYS software is used for building a finite element model with the safe distance between the concealed karst cave and the mountain tunnel, tunnel construction sequence is simulated to solve finite elements, plastic strain energy corresponding to the rock stratum between the concealed karst cave and the mountain tunnel after distance reduction each time is calculated, the change sequence between the distance between the karst cave and the mountain tunnel and the plastic strain energy of the rock stratum between the concealed karst cave and the mountain tunnel is built, an energy mutation characteristic value is further calculated, and when the energy mutation characteristic value is smaller than or equal to zero, the safe distance between the concealed karst cave and the mountain tunnel is output. The energy mutation of the rock stratum between the concealed karst cave and the mountain tunnel is taken as a criterion of the safe distance, the determined safe distance is smaller than the safe distance determined with a conventional plastic zone criterion, and the method overcomes the defects that traditional analog calculation of the safe distance between the concealed karst cave and the mountain tunnel on the basis of plastic zone cutthrough is troublesome in process and unreasonable in result, ensures safety of the karst mountain tunnel, and reduces occurrence probability of karst accidents.
