In the construction process of the high-speed railway, the foundation design of each building part is of great significance to guarantee the long-term stable operation of the railway. This paper takes the Jinan West Station Beijing-Shanghai high-speed railway station project as the research object, and analyzes the influence of the foundation dewatering system on the settlement of composite foundation. Firstly, the background and significance of the project are introduced, and then the literature review is summarized, and the relevant research results of composite foundation and foundation dewatering system are proposed. Furthermore, numerical simulation method is used to establish the numerical model of composite foundation, and the influence of different dewatering schemes on the settlement of composite foundation is analyzed by considering the influence of foundation dewatering on the settlement of composite foundation. Finally, the research results are discussed and analyzed, and relevant conclusions and suggestions are put forward.【Keywords】精品文档---下载后可任意编辑Beijing-Shanghai high-speed railway; Jinan West Station; foundation dewatering; composite foundation; settlement influence; numerical simulation
