摘要
结合赣泰高速公路K236高边坡开挖防护实例,采用FLAC模拟边坡开挖和防护过程,并通过对模拟过程的分析,揭示滑坡形成的机理及发展演变的过程。通过对防护前后边坡应力图、位移图及相关数据的比较,对边坡的稳定性及防护后效果做出评价,为采用合理的防护结构提供依据。
With reference to practice in Ganzhou - Taihe Expressway K236 high slope excavation ＆ protection, FLAC simulates the side slope excavation and protection process. Through analysis to simulation proess, it discloses system of land slide formation and process of development and transition. Through comparison among front and rear slide slope stress diagram, displacement diagram and relevant data, it gives evaluation to side slope stabilization and post protection effect, which offers basis for adopting rational protective structure.
