微型钢管桩用于滑坡治理及理论分析

结合长阳县红岩溪滑坡的地质结构特征,对边坡治理工程中的微型钢管桩设计进行了改进,探讨了微型钢管桩的抗滑机理,并通过设计和计算证明，用微型钢管桩能有效地治理滑坡；针对微型钢管桩的抗滑机理尚未形成一套较为成熟的理论，文中以两种计算方法对比分析了微型钢管桩加固边坡的稳定性，结果表明，采用类比法进行微型钢管桩设计是适宜的。

Landslide Treatment with Micro Steel Tube Pile and Theoretical Analysis

Combined with geological structural characteristics of landslide in Changyang Hongyanxi,micro steel tube pile design is improved in slope treatment engineering and the anti-slide mechanism of micro steel tube pile is discussed.Through design and calculation,it is proven that micro steel tube pile is effective in landslide treatment.For the theory of anti-slide mechanism of micro steel tube pile has not been matured,this paper analyzes the stability of micro steel tube pile reinforced slope through comparison of two calculation methods.It is indicated from the result that method of analogue is proper for micro steel tube pile design.
