Comparative Analysis of Bearing Capacity of Rock-Socketed Piles and Discussion on Optimization Measures
In practical engineering,the selection of geotechnical parameters and the design of foundation schemes significantly impact the project cost.This paper relies on the technical data related to rock-socketed piles from a project in Xiushan,Chongqing,and conducts a comparative analysis of the bearing capacity of piles using both the finite element method(FEM)and the empirical parameter method.The analysis reveals that under the same engineering conditions,the differences in the proportions of side friction and end resistance calculated by the FEM and the empirical parameter method can be both positive and negative,resulting in significant variations in the characteristic values of pile bearing capacity.Specifically,the FEM results are more than 20%higher than those obtained by the empirical parameter method.Consequently,it is proposed that optimizations should be made in terms of geological parameters and pile types.Through the comparative analysis of the bearing capacity of rock-socketed piles and the discussion on optimization measures,this paper aims to provide references for similar engineering practices.
