Study on methods for deep foundation pit supporting in Beijing

摘要

Slope supporting piles and enlarged prestressed anchorage was used to support the deep foundation pit in Beijing which is a complicated engineering and influenced by many factors that locating in the midtown of Beijing city and nearby the construction, traffic trunk and underground pipelines based on the hydrological datum and geological conditions through the specific analysis of the actual conditions, surroundings and geological conditions of the site. Then taking full advantages of the large resist pulling force of single anchorage, small displacement and high reliability of enlarged prestressed anchorage and ensures the engineering be carried out safely and successfully.
