Abstract

The understanding of stratigraphic structure, site conditions, and construction impacts in geotechnical engineering projects has long been limited by fragmented data, two-dimensional representations, and professional segregation. This hinders the formation of a unified understanding and effective decision-making in investigation and design, leading to delayed risk identification and cost control. 3D visualization intelligent systems integrate investigation, design, and construction data, intuitively presenting subsurface spatial morphology and uncertainty distribution. They support scheme comparison, risk front-loading, and collaborative management, thereby enhancing design quality and implementation efficiency. This paper constructs the architecture of a 3D visualization intelligent system for engineering investigation, proposes a multi-source data acquisition and fusion process, establishes methods for geological model and parameter field representation, conducts stability and deformation analysis, and combines construction simulation and monitoring feedback loops. This achieves systematic application in information integration, collaborative design, and risk control.
