Application of Foundation Coefficient Method in Calculation of Internal Forces of Stabilizing Piles in Rock Mass

Some problems are pointed out when traditional foundation coefficient method is applied to the calculation of internal forces of stabilizing piles in rock masses.For these,firstly,the calculation formulae of internal forces of rigid stabilizing piles are derived based on their characteristics of the subjected forces and displcements.Secondly,the finite differential method based on foundation coefficient is presented according to the characteristics of elastic stabilizing piles.The calculation formulae to be used in theanalysis of internal forces of elastic stabilizing piles are also derived.Meanwhile,the calculations of internal forces of rigid and elastic stabilizing piles are programmed based on these formulae by using mathematic software i.e. MATLAB.All the calculations can be performed,and reasonable visual figures can be transformed according to the calculation results by the program.For rigid stabilizing piles,calculation results are precise.For elastic stabilizing piles,the precision of calculation results is better than that of traditional method by means of tables.The visual figures of the calculation results are helpful to construction design of stabilizing piles.
