Foundation pit supporting analysis method using prestressed hollow pile
The invention provides an analysis method for a prestressed hollow pile for foundation pit supporting. The method comprises the following steps: acquiring static stress data of the prestressed hollow pile in foundation pit supporting; analyzing the static stress data based on a preset static stress analysis model of the prestressed hollow pile to obtain static distribution stress information; obtaining a dynamic load acting on the prestressed hollow pile; constructing a dynamic stress equation set of the prestressed hollow pile based on the dynamic load and a preset finite element model; solving the dynamic stress equation set to obtain dynamic distribution stress information; stress coupling analysis is conducted on the basis of the static distribution stress information and the dynamic distribution stress information, and supporting effect analysis data used for representing supporting stress distribution of the prestressed hollow pile foundation pit are obtained. The stress distribution and the supporting effect of the prestressed hollow pile in the foundation pit supporting can be evaluated more comprehensively, and the safety and the stability of foundation pit construction can be ensured.
