摘　　要：为了优化濑溪河堤防工程边坡灌注桩的设计深度,本文提出采用有限元软件PLAXIS对3种不同桩体深度下堤防在稳定渗流期和水位消落期两种工况下的边坡稳定性、滑裂面和桩体弯矩进行计算分析。经计算,该工程断面灌注桩最优设计深度为12m,既能满足稳定性要求,又更加经济合理。计算过程可为同类堤防工程的加固设计提供参考。! In order to optimize the design depth of Laixi River levee engineering slope cast-in-place piles, it is proposed that finite element software PLAXIS can be adopted for calculating and analyzing slope stability, critical slip surface and pile bending moment of embankments under three different pile depth during stable seepage period. The optimal design depth of the engineering section grouting pile is 12m after calculation. It can meet the stability requirement on the one hand, and it is more economical and reasonable on the other hand. The calculation process can provide reference for the reinforcement design of similar embankment projects.
