| Abstract: | In order to implement partial removal of original footing when there was interference between original footing and that of newly-set up equipment in the construction,different feasible schemes were compared with each other and,finally,a strategy of foundation reinforcement was adopted,where unloading of footing bottom stakes as well as enwrapping were to be used.During the process of computation the traditional Ranken's earth pressure theory and that of Coulomb's were reasonably simplified. In the process of construction the sediment and displacement were strictly controlled,so that the construction safety was guaranteed completely and good reinforcing effect was obtained. |
