A Caculation Method Discussion of Vertical Bearing Capacity on End Post-Grouted Drilled Piles Jie Liu1,2,a and Yanyan Zhang1,b 1School of Civil Engineering,Tianjin University, Tianjin, 300072,China 2 Key Laboratory of Coast Civil Structure and Safety, Ministry of Education, Tianjin, 300072,China atdlj5536@sina.com, bchltazhyy@126.com Keywords: End Post-Grouted Drilled Piles; Bearing Capacity; Circular Truncated Cone Model; Caculation Formula Abstract.
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.
(3)According to a certain number of engineering cases,the ultimate bearing capacity value for single-pile derived from the formula this article mentioned can fit the static loading test results well,which is more simple and can provides a certain engineering practical reference value.
