| Abstract: | High-rise buildings have been built more and more in recent years in China.However,technical preparations in geotechnical and foundation engineering are not enough to face the challenge yet.Loading test data of representative skyscrapers of Beijing CCTV Tower,Tianjing 117 Tower and Shanghai Center are discussed and load transfer mechanism,load-settlement behavior,variation characteristics of shaft resistance and reinforcement effect of post grouting for cast-in-situ pile are analyzed.The testing data and an... |
