Influence analysis of vehicle dynamic load on foundation pit enclosure and suggestion
-
Abstract
When vehicle dynamic load is around the foundation pit, it is classified as the general hazard source by the current industry safety standard. The partial collapse of a foundation pit in Hangzhou led to the collapse of the adjacent road, and investigation found that the vehicle dynamic load was the cause of the accident. In reference to the accident, this paper discusses the influence law of vehicle dynamic load on the foundation pit enclosure structure through analysis of the cause and comparison with the current standard code. It is proposed to raise vehicle dynamic load as a major hazard source, and solve the problems from the aspects of cross-industry research, increasing the external load limit of the foundation pit, improving foundation pit monitoring and on-site control. At the same time, it is suggested to take vehicle dynamic load as the research subject to find out the mechanical model, summarize the influence law, give targeted measures, and add them to the current standard and specification.
