3D Circular Dam Structure Model with Access Gallery

This drawing depicts a large circular dam structure with a diameter of approximately 150 meters, presented as a 3D solid model. The structure features a main circular body shown in white outline with internal geometric reference lines in red and green delineating the structural profile. At the top of the structure, there appears to be an access gallery or control room (shown in yellow) with vertical elements that likely represent monitoring equipment or ventilation systems. The dam design employs a curved face geometry that optimizes pressure distribution across the structure – a critical consideration for hydraulic load management in large-scale water retention facilities. The model includes both the primary containment structure and operational components, revealing the relationship between structural elements and monitoring systems required for dam safety compliance.
