What is it about?

As a technology that can improve the bearing capacity of pile foundation, combined post-grouting has been widely used in engineering. In this paper, field tests of two combined post-grouting piles are reported, and their effects before and after application in the cohesive soil layer are compared.

Why is it important?

At present, there are few reports on the field test of combined post-grouting pile in cohesive soil layer. Our study has accumulated important test data for this field, which can provide reference for the design and construction of composite post-grouting pile in cohesive soil layer.


I hope this article will arouse more people's interest in the field of pile foundation, pile foundation is not as simple as imagined, despite the history of human construction is very long, but our construction level is still improving.
