摘要
Based on a thorough study of the deformation mechanism for gravel pile composite ground under flexible foundation,a new method for gravel pile composite ground settlement analysis is set up by using the soil displacement in a unit cell mode.The analysis method can not only reflect the interaction between pile and its surrounding soils as well as the characteristics of slip between piles and soil,but also consider the influence of the lateral deformation of the gravel pile in composite ground settlement analysis.The engineering examples show that the method proposed in this paper is of feasibility and rationality.
