Safety risk assessment of heritage buildings in metro construction based on SPA theory: a case study in Zhengzhou, China

Abstract

While the urban rail transit systems have been developed rapidly, the nearby heritage buildings and historic sites are facing possible threats of unexpected damages. In particular, a rail project has a potential impact on numerous heritage buildings and sites in an old city. Thus, to better protect these heritage buildings and sites, it is crucial for decision-makers to be able to rapidly and accurately evaluate these threats. Based on Set Pair Analysis (SPA) theory, this study developed a risk assessment model to assess the safety of heritage buildings adjacent to metro construction. In this model, the risk levels of adjacent heritage buildings are ranked. Moreover, this study establishes an assessment index system comprising 16 individual indexes among four categories related to heritage building, metro, soil, and management. The index system determines the interval values for each evaluation factor. To improve the reliability of the index weight, a linear weighting method was adopted. In this study, both subjective weights calculated via the Analytic Hierarchy Process (AHP) and objective weights calculated by the Clustering Weight Method (CWM) are analyzed comprehensively. Moreover, a case study was conducted by applying the proposed assessment model into assessing the structural safety risk of a heritage building adjacent to the Zhengzhou Metro Line Three. It was found the results of the proposed model were consistent with the Matter-Element (ME) method. The proposed model can be used to provide decision-making support for controlling risk on similar projects.

Assessment Of Economic Security Of Territorial Systems Based On The Membership Function

“…To calculate the weights of indicators during their integration, the method of pair-wise comparisons, the method of analyzing hierarchies and the method of clustering weights are used (Wang et al, 2020).…”

Environmental Risk Assessment of Subway Station Construction to Achieve Sustainability Using the Intuitionistic Fuzzy Analytic Hierarchy Process and Set Pair Analysis

“…us, they proposed an assessment model of blasting safety based on the SPA. Wang et al [26] considered the uncertainty of the risks caused by subway construction to nearby buildings and proposed the use of SPA to evaluate the safety of cultural relics adjacent to subway construction. e results show that the effectiveness of the model provides decision support for controlling the risks of similar projects.…”

Strategic Planning of Regional Development as Instrument of Ensuring Stability and Economic Security of a Territory

“…Within the framework of goal-setting, the region is considered as the middle link in the hierarchy of social-and-economic systems: the macroeconomic goals of regional development coincide with the goals of the national system; mesoeconomic goals of regional development aggregate the goals of micro-level entities (enterprises, business entities) in a sectoral context. The setting of goals in the strategic planning system of the region is based on the long-term prospects for the development of the territory, considering the resources available to it, the possibilities of activating the potential and overcoming probable threats [1][2][3][4][5].…”
