Abstract EN
Numerous excavation practices have shown that large discrepancies exist between field monitoring data and calculated results when the conventional symmetry-plane method (with half-width) is used to design the retaining structure under asymmetrical loads.
To examine the characteristics of a retaining structure under asymmetrical loads, we use the finite element method (FEM) to simulate the excavation process under four different groups of asymmetrical loads and create an integrated model to tackle this problem.
The effects of strut stiffness and wall length are also investigated.
The results of numerical analysis clearly imply that the deformation and bending moment of diaphragm walls are distinct on different sides, indicating the need for different rebar arrangements when the excavation is subjected to asymmetrical loads.
This study provides a practical approach to designing excavations under asymmetrical loads.
We analyze and compare the monitoring and calculation data at different excavation stages and find some general trends.
Several guidelines on excavation design under asymmetrical loads are drawn.
