Identification and Assessment of Subway Construction Risk: An Integration of AHP and Experts Grading Method

Abstract

Qing Dao is one of the earliest cities that included the idea of subway construction into the city’s transportation plan. However, the construction period of a subway project is long, and the uncertainties caused by the geological conditions and surrounding environments are huge, thus a risk assessment method in subway construction is essential. To ensure the tunnel safety, many researchers have raised different methods for risk assessment. The process of risk assessment can be characterized in three steps: (1) data acquisition; (2) complete the uncertainty model; (3) evaluate the possible risk during the construction. This paper introduces a novel risk assessment method that combines the Analytic Hierarchy Process (AHP) and Experts Grading Method (EGM). The advantage of AHP is that it can quantify the qualitative factors, inspect and reduce the subjective influence to a certain extent, and make the evaluation more scientific. As for the EGM, simplicity and directness are the main characteristics. Assisted by this method, proper measures can be taken to eliminate the potential risk. The integrated method was implemented during the construction of Taishan Road Station of Qingdao Subway to evaluate the potential risk. With the help of this integrated method, the general risk sources during the construction period are well marked and the control measures corresponding to the risk sources are provided.

Safety Risk Evaluation of Construction Site Based on Unascertained Measure and Analytic Hierarchy Process

“…e construction site risk assessment needs feasible methods, and the commonly used safety assessment methods at home and abroad mainly include safety checklist (SCL) [27,28], fuzzy comprehensive evaluation method (Fuzzy) [9,29,30], analytic hierarchy process (AHP) [31][32][33], fault tree analysis (FTA) [34,35], support vector machine (SVM) [36,37], and Fuzzy-Analytical Hierarchy process (FAHP) [38]. ese methods not only provide the theoretical basis for the production practice, but also lay the foundation for the subsequent theoretical research.…”

Sustainability of Business through Project Risk Identification with Use of Expert Estimates

“…Liu [88] pointed out that the prediction of possible future risks of a project is based on existing data, calculation theory and experience, so that the reliability and credibility of its results depend to a large extent on the practical experience and knowledge of the evaluators.…”

“…It has the unique capability to distill the insights and intuitive judgments of experienced professionals into tangible data that can guide pivotal decisions. Since its inception in the 1970s, the AHP has become an indispensable tool for navigating complex decision-making landscapes, applicable in a wide array of fields, from shaping public policy to crafting nuanced business strategies [99][100][101][102][103][104][105][106][107][108][109].…”
