In this paper,a new calculation method of single-row anti-slide pile with single -row anchor is given,it is foundation coefficient and pre-stress calculation met hod.On that basis,a new finite pole element method is given also.These calculat ion methods can be used to the preliminary design of anti-slide pile and common engineering.The practical application of these calculation methods showed that they are simpler than conventional methods,and are in accordance with practicals ituation.
