Description

Technical Field

[0001] The present invention belongs to the technical field of seismic resilience assessment, and particularly relates to a method, system, device, and medium for assessing the seismic resilience of an in-river overhead vertical frame wharf in a high-intensity seismic area. Background Art

[0002] In the upper reaches of the Yangtze River, large-scale cascade hydropower stations such as Xiangjiaba, Xiluodu, Wudongde, and Baihetan have been built on the main stream of the Jinsha River. These hydropower stations mainly focus on power generation, and also have comprehensive benefits such as flood control, sediment interception, improving downstream shipping conditions, and developing navigation in the reservoir area. With the impoundment operation of the reservoir, the natural channelization of the waterway and the navigation conditions will be greatly improved. Therefore, by building wharves in the reservoir areas of these power stations, the deep-water waterways formed by the power station construction can be utilized to develop waterways connecting the main line of the Yangtze River, which is conducive to improving the comprehensive transportation system in the lower reaches of the Jinsha River and better serving the regional economic and social development.

[0003] Due to the complex geological conditions in these areas, geological disasters occur frequently. In particular, the construction sites of wharves are often located in the influence areas of active fault zones and belong to high-intensity seismic areas, where strong earthquakes may occur during the service life. In addition, the foundation of the wharf is usually a thick gravel covering layer. Under the action of strong earthquakes, due to the increase in pore water pressure, the modulus and strength of the foundation will weaken, resulting in large deformations of the foundation, which will affect the bearing capacity of the wharf foundation or the stability of the bank slope. Past earthquake disasters at home and abroad have shown that wharf structures are prone to damage under the action of strong earthquakes, which will bring huge direct and indirect economic losses. Since there are few ports in high-intensity seismic areas in China, there is little research on the seismic performance of wharves.

[0004] On the other hand, with the development of the economy and society and the acceleration of the urbanization process, on the basis of ensuring post-earthquake safety, "resilience", which measures the ability of modern cities and even the whole society to maintain or restore their original functions after disasters, has become a research hotspot. The essence of the functional recovery of a macro city or community is the recovery of a large number of subsystems. Judging its recovery function in the state of partial damage and establishing a post-disaster recovery model and quantitative evaluation method applicable to special engineering systems and specific damage states can obtain more accurate judgment bases and resilience models, which have important application values for rapid post-disaster recovery and resource scheduling planning.

[0005] In the current research field of the seismic resistance of wharf structures, theoretical analysis and quantitative evaluation mainly focus on the real-time disaster risk assessment of wharves under the action of earthquake disasters, without considering important indicators related to the seismic resilience of wharves, such as earthquake economic losses, the degree of function loss, and recovery time. In particular, there is no report in the literature on the evaluation method and system for the seismic resilience of in-river wharves in high-intensity seismic areas, which is a blank in this field. Summary of the Invention

[0075] Determine the seismic ground motion attenuation relationship suitable for the wharf area, conduct a probabilistic seismic hazard analysis of the engineering site, and obtain the bedrock seismic ground motion parameters and bedrock seismic ground motion response spectra at different levels of exceedance probability of the engineering site.

[0076] S3. Conduct a seismic vulnerability analysis of the wharf.

[0077] Specifically, according to the design data of the wharf and the site geotechnical engineering investigation report, establish a soil-pile-structure finite element model of the wharf. Among them, the soil body, quay wall and reinforced concrete slab adopt solid elements, and the reinforced concrete columns, beams and pile foundation adopt beam elements.

[0078] Select a suitable material constitutive model. Among them, the reinforced concrete columns, beams and pile foundation units adopt fiber cross-sections, the soil, concrete and steel bars adopt non-linear models, and the quay wall adopts a linear elastic model.

[0079] Considering the uncertainties in the dock geometry and materials, the Latin Hypercube Sampling method is used to determine their parameter values.

[0080] Considering the randomness of ground motion, a certain number (no less than 11 groups are selected) of actual ground motion records and artificial simulated earthquake acceleration time history curves that can represent the seismic hazard of the dock site are selected. Among them, the number of actual strong motion records should not be less than 2 / 3 of the total number.

[0081] Apply the IDA method to conduct elastoplastic time history analysis of the dock finite element model considering the coupling effects of various uncertainty factors.

[0082] Extract the engineering demand parameters from the results of the elastoplastic time history analysis, and establish the relationship between the engineering demand parameters of the dock and the ground motion intensity index.

[0083] Calculate the seismic vulnerability curves of the dock components and the slope at different performance levels, and construct a seismic vulnerability database for structural components, non-structural components, and slopes.

[0088] Specifically, according to the engineering demand parameters of the dock, combined with the seismic vulnerability database, determine the damage state and occurrence probability of structural components and non-structural components, and the stability state and instability occurrence probability of the slope under the action of an earthquake at the set level.

[0089] Apply optimization theory to conduct optimization analysis of the post-earthquake repair path of the dock, and determine the optimal post-earthquake repair path.

[0090] According to the determined post-earthquake repair path, predict the repair cost, repair time, and casualties of the dock under the action of an earthquake at the set level.

[0097] The normalized wharf performance loss function is defined as the sum of the direct loss and the indirect loss, as shown in Equation (3):

[0098] L(IM, T RE ) = L D (IM, T RE ) + αL I (IM, T RE ) (3)

[0099] where L I is the indirect loss; α is the weighting coefficient; L D is the direct loss.

[0100] The direct loss is shown in Equation (4):

[0101]

[0102] where P j is the conditional probability that the structural state reaches or exceeds the damage state j when the ground motion intensity is IM; C s,j is the repair cost required when the structure appears in the damage state j; I s is the cost of demolishing and reconstructing the structure; γ iis the annual discount rate; δ i is the annual depreciation rate; T i is the time interval from the initial investment of the wharf to the occurrence of the earthquake.
