Abstract
The paper discusses and researches the influence of foundation pit dewatering of Ji'nan west railway station on the settlements of composite foundation of Beijing - Shanghai high-speed railway by means of field tests. Results showed that foundation pit dewatering had different degrees of effect on the settlements of composite foundation in the same cross-section with different pile lengths. The longer pile length the smaller the impact. The impact of 35 m PHC pile was less than 25 m CFG pile, and the impact of 25 m CFG pile was less than 15 m CFG pile.关键词
