摘要
小口径组合抗滑桩在滑坡工程应用中的设计理论和计算方法属实践性很强的新领域,多采用工程类比法。结合永州市冷水滩区某滑坡应急治理工程,介绍了小口径组合抗滑桩加固技术,通过反演分析确定了滑带岩土体物理力学参数指标,计算了不同安全系数下的滑坡推力,并进行沿滑面抗剪以及结构抗力验算。工程实际应用表明,小口径组合抗滑桩实现了较好的应急处置效果。
The design theory and calculation method of anti-sliding pile in Landslide Engineering belong to a new field with strong practicality,and engineering analogy method is mostly used.In this paper,combined with a landslide emergency control project in Lengshuitan area of Yongzhou city,the reinforcement design method of small-diameter steel pipe composite structure is described.Firstly,the physical and mechanical parameters of rock and soil mass are determined by back analysis.Then,the resisting force of anti-sliding pile group required under different safety factors is calculated.Finally,the shear resistance along the sliding surface and structural resistance is checked.The practical application of engineering shows that the small-diameter steel pipe composite structure has achieved good control effect in Emergency Control for Abrupt Geo-hazards.
