摘要
Abstract
Pile-plate retaining walls have been adopted in multiple river regulation projects due to their simple and reliable structure,small construction footprint,and low construction costs.Pile-plate retaining walls are often arranged in soft clay foundations,and the mechanical properties between piles and soil are relatively complex.This paper aims to clarify the influencing factors of soil arch effect between piles and soil,and uses numerical simulation methods to study the effects of pile spacing,soil shear parameters,and friction coefficient between piles and soil on soil arch effect.The results indicate that the soil arch effect is strongest when the pile spacing is 2-5 times the pile width;The soil arch effect increases with the decrease of soil cohesion and the increase of internal friction angle;The larger the friction coefficient between piles and soil,the stronger the constraint of the pile on the soil between piles,and the stronger the reverse stress arch.The research results can provide reference for the design of pile-plate retaining walls.关键词
