Abstract

Highway expansion projects involve slope demolition, which works differently from the newly built highways. The risk situation of slope demolition construction under the condition of uninterrupted traffic is more complicated. Considering factors such as the demolition of existing support structures and uninterrupted traffic flow, this paper investigates the construction risk assessment methods for slope demolition in highway expansion and reconstruction projects. The main conclusions of the study are as follows: (1) Project specificities should be considered in the risk assessment of slope construction for highway reconstruction and expansion projects, such as existing slope conditions, demolition methods, and environmental factors, to further enhance the practicality of the assessment method. (2) In terms of index weights, the demolition method accounts for the highest proportion, followed by geological conditions and slope conditions. (3) Case studies in the paper reveal that the risk level of slope construction is level III, indicating a high level of risk. Therefore, prior to construction, optimization should be done, effective personnel management and construction monitoring must be strengthened in the construction process, and data changes should be updated in time.
