Application of PCC in Highway

摘要

Rigid pile composite foundation is often used as an effective ground treatment method in the construction of highways. The PCC (cast-in-place thin-wall concrete piles) composite foundation is more and more frequently used in highway ground treatment. The research conducted on this type of foundation is very little. This paper highlights the use of PCC in Yan-Tong highway. The design, construction and quality test of this method are introduced. Test results show that the pile quality is good and its bearing capacity is relatively high.
