Abstract: A set of three-dimensional engineering investigation information system was built based on the practical engineering investigation application need and preliminary work. The system was composed by two major parts, two-dimensional subsystem and three-dimensional modeling subsystem.Many functions were achieved such as the fast flexible 3D construction of geological interfaces, internal attributes of geological bodies and engineering structures. And the data conversion interfaces to other calculation and simulation analysis software were also provided. Through practical test the system proved efficient during the engineering investigation.

摘要: 开发了一整套三维工程勘察信息系统。该系统主要由二维工程辅助建模子系统和三维工程建模子系统两大部分组成,实现了地下地质体边界、地质体内部属性、工程体构筑物等模型的快速、灵活三维构建,并为模拟分析计算留有充分的数据转换接口。实践证明该系统在工程勘察高效化、直观化等方面具有良好的应用前景。
