A Caculation Method Discussion of Vertical Bearing Capacity on End Post-Grouted Drilled Piles
This article establishes a circular truncated cone model of the post-grouted induration end,brings forward a integrative influence coefficient and edtablishes a simple vertical bearing capacity caculation formula of post-grouted piles with the broaden diameter caculating the end resistance of the pile, which has considered the influence of mortar volumn.According to a certain number of engineering experiment,the tesults derived from this formula can fit the static loading test bearing capacity of the post-grouted drilled piles well,which can provides a certain engineering practical reference value.
