Finally , the design and calculation method of prestressed anchor cables of anti - slide piles is studied . on basis of foundation coefficient method and finite element method , the anti - slide piles are dispersed to be rod element
2.
Secondly , the foundation coefficient method , which is the calculation method of anti - slide piles , is simulated by finite element method . the large scale finite element software ansys is adopted to establish finite element model of anti - slide piles and prestressed anchor cables
3.
Besides experiments , the present domestic and abroad study on anti - slide pile is mainly analysis by traditional cantilever beam method , foundation coefficient method and elastic mechanic method . on the basis of previous studies , this paper carries out a research on relevant design and calculation theory about anti - slide piles , comprising the interaction between anti - slide piles and rock and soil of side slopes , the soil arching model of anti - slide piles and the internal stress calculation method of prestressed anchor cables
4.
By means of the measuring the natural frequencies of a beam on a elastic foundation together with the transfer matrix method and the computer algebraic language �� the paper deduces the high - order equation �� which contains unknown quantity of the stiffiness of supports . this method �� the validity of which has feen verified by experiments �� can be applied to identifying the foundation coefficient
