Complicated design of the foundation, west tower asymmetric part of the connection led to the difficult structural design. This paper focuses on the application of post grouting for cast-in-situ pile and stiffness to reduce differerntial settlement of piled raft foundation technology ,that creat a significant economic and social benefits.Keywords: post grouting for cast-in-situ pile; stiffness to reduce differerntial settlement
