Analysis & Research on the Parameter Sensitivity to Bearing Capacity of Autocrane Operation Site

Abstract:

Autocrane has strict requirement for the bearing capacity of operation site during the process of lifting and transferring. To evaluate the intensity stability of operation site, the detailed analysis to ultimate bearing capacity of operation site must be carried out and find out the sensitivity factors which influencing the bearing capacity of operation site. In this paper, based on the analysis of computation pattern of ground bearing capacity, the ultimate bearing capacity is deduced through considering the shearing strength of superstratum under circular load ground. Simultaneously, based on single factor sensitivity analysis method, the sensitivity expression of cohesion force, internal friction angle and superstratum thickness to limiting bearing capacity is analyzed and calculated, and the influence regularities of the ultimate bearing capacity of operation site, due to the sensitive parameters, is discussed.
