三峡库区抗滑桩优化设计方法及应用研究

以抗滑桩受力分析为核心,对抗滑桩桩后推力和桩位的确定进行了优化;论文一方面提出计算抗滑桩的设计推力时考虑抗滑桩对桩后岩土体的作用力,另一方面提出设桩处推力差值最小点为抗滑桩的合理位置。再结合工程实例运用优化设计理论,并以治理效果验证了这种优化设计的可靠性。

Study on Optimization Design Method and Application of Anti-slide Pile in Three Gorges Reservoir Areas

Focusing on anti-slide pile stress analysis,this paper optimizes the determination of anti-slide pile thrust and pile location.On the one hand,it puts forward that the action of anti-slide pile to rock mass shall be considered in calculation of design thrust of anti-slide piles;on the other hand,it advances that the minimum thrust difference shall be the rational location of anti-slide.Combined with engineering practice,with optimization design theory,it verifies the liability of this optimization design ba...
