摘要
采用有限元法对板桩结构受力特点进行了分析,结果表明,前墙入土深度和抗弯刚度对板桩结构受力特性有显著影响。入土深度一定时,前墙位移、陆侧弯矩、锚碇墙陆侧弯矩和拉杆拉力均随前墙抗弯刚度的增加而减小,前墙海侧弯矩随之增加;前墙抗弯刚度一定时,前墙陆侧弯矩、拉杆拉力随入土深度增加而减小,入土深度大于某值后,对各项影响较小。
The stress characteristics of the sheet pile structure is analyzed by using the finite element method. The results show that the embedded depth and flexural rigidity of front wall have a significant impact on the stress characteristics of the sheet pile structure. When the embedded depth is constant, the displacement, bending moments of landside of front wall, bending moments of landside of anchor wall and draw rod pull decrease and the bending moment of the seaside of front wall increases with the increase in the flexural rigidity of front wall; when the flexural rigidity is constant, the bending moments of landside of front wall and the draw rod pull decreases with the increase of the embedment depth; when the embedded depth increases to a critical value, the impact turns less.
