The Optimum Design Of The System On Anchor Rope Anti-slide Pile

Anchor rope anti-slide pile is a new-type support forms on the basis of developed anti-slide pile. Anchor rope at the top of anti-slide pile can supply a tension for anti-slide pile, make the applied loads and the stresses of it distribute more reasonable, thus, the dimension of anti-slide pile can be reduced. So, it is important theory significance and use valuable to study deeply the optimum design question, it will improve in the sufficiency of the traditional design methods in great degree, making the target have enough safety degree as well as economic. As a result, it will make the design and calculating method become more reasonable.Firstly, the article analyses and calculates the internal force and deformation of the system on anchor rope anti-slide pile. As a result, a new method is used: we consider the internal force and deformation of anti-slide pile when deliberating the structure-soil interaction, so as anchor rope too, and consider the compatibility of deformation between the anti-slide pile and anchor rope, a new method to calculate internal force and deformation on anchor rope anti-slide piles is put forward by the interaction of anchor rope anti-slide piles.On the other hand, the article introduces optimum design on the basis of extinguishment loss expectations, and uses it in the system of anchor rope anti-slide pile, the article analyses new reliability on anchor rope using the linear second order moment method and partial coefficient method, and by the use of the approximate relationship between engineering costs and reliability, decide total reliability of the system on anchor rope anti-slide pile, obtain optimal solutions by seeking total reliability of the optimal distribution system between anchor rope and anti-slide pile.At last, through studying the controlling schemes of the landslide engineering, it verified the optimum design method which mentioned in the paper. At the same time, it also proved that it is feasible to apply the theory of the optimum...
