论文摘要
浸入式的等几何边界元素方法被提出，并应用于地下发掘的模拟。非均匀的理性B型（NURB）用于对几个参数的复杂几何形状的准确定义。沉浸式技术应用于自动生成细胞网。这允许考虑异质和各向异性的地面条件以及非线性物质行为。在一个实际示例上，用户友好和准确性得到了证明。
The immersed isogeometric Boundary Element Method is presented and applied to the simulation of underground excavations. Nonuniform rational B-splines (NURBS) are used for the accurate definition of complex geometries with few parameters. Immersed technology is applied to automatically generate cell meshes. This allows heterogeneous and anisotropic ground conditions as well as nonlinear material behaviour to be considered. On a practical example the user friendliness and accuracy is demonstrated.
