| Abstract: | Based on the theoretical calculation of the settlement of a building near a foundation pit somewhere in the city of Jianyungang, Jiangsu Prcvince and by comparing the measurement with the of settlement derived from field survey, the cause of the difference between the two measurements is pointed out. As a result of the further analysis, the factors influencing the settlement of the building surrounding the foundation pit are summeriyed. According to the values practically measured, the way the settlement of a building surrounding a foundation pit is influenced by distance between the building and the retaining pit, the arrangement of the retaining pit, the time domino effect, and press grouting, etc. were all carefully compared and analysed. A couclusion drawn may play a prectical role in coustruction and well help improve the foundation pit design. |
