| description | As a common water conveyance structure, aqueduct is widely used in cross-regional water conveyance and diversion projects. However, large double-trough aqueduct structures are prone to damage under earthquake, resulting in water leakage and even interruption, endangering the safety of people’s lives and property in surrounding areas. In this paper, the nonlinear reinforced-concrete material program is compiled based on the FORTRAN language. Taking the Shuangji River aqueduct project as an example, the numerical model of the fiber beam element of the double-trough aqueduct structure is established, and the nonlinear dynamic time-history response analysis of different ground motion inputs is carried out. Based on the midspan displacement and acceleration time history, pier bottom bending moment and shear force time history, the nonlinear response law of large aqueduct structure is studied. A criterion for determining the overall collapse of aqueduct structure based on effective energy is proposed. The correctness and feasibility of the nonlinear numerical model of the aqueduct structure and the dynamic catastrophe analysis method are verified by focusing on the overall seismic response of the aqueduct structure and the material yield status of key parts, and comparing with the collapse criterion based on the limit value of pier top displacement angle. The conclusions will provide a basis for seismic analysis, optimization design, and operation and maintenance safety assessment of large aqueduct structures and have important theoretical significance and engineering application value. |
