| 摘 要： | 以云南省牛栏江红石岩堰塞湖永久性整治工程为依托，采用基于变尺度混沌优化算法的山体震裂缝多参数优势分组方法，考虑山体震裂缝的走向，长度，宽度，深度，充填物性质和充填度6个重要参数，通过度量震裂缝之间的相似性建立目标函数，运用变尺度混沌优化算法搜索目标函数的最优解来确定聚类中心，对库区右岸王家坡潜在不稳定震裂山体上的82条震裂缝进行了研究。研究结果表明:运用此算法可以快速将具有多参数相似性的震裂缝划分为组，优化了传统的依据震裂缝的产状数据和现场调查资料定性分析的分组方法。通过对现场震裂缝资料反复核对，验证了计算方法的准确性。

Study on Multiparameter Dominant Partitioning of Seismic-related Moutain Fracture Based on Mutative Scale Chaos Optimization Algorithm |
| |
| Abstract: | Relying on the permanent regulation works of Hongshiyan Barrier Lake at Niulan River in Yunnan, this paper used the method for multiparameter dominant partitioning of seismic-related moutain fracture, which is based on mutative scale chaos optimization algorithm, and by taking 6 important parameters into consideration, including the fracture’s orientation, length, width and depth, the properties of filling material thereof, and the filling percentage, established an objective function by way of measuring the similarity among the seismic fractures; then, sought the optimal solution of the function by this mutative scale chaos optimization algorithm to determine the clustering center; thus made the study on the 82 seismic fractures on the fractured mountain of latent instability at Wangjiabo Slope at the right banks in the reservoir area. The result shows that the algorithm herein can partition the seismic fracture of multiparameter similarity rapidly, therefore optimize the traditional partitioning method which depends on seismic fracture’s occurrence and field investigation data for analysis. At last, by repeatedly checking the field data of seismic fracture, the accuracy of the calculation method herein is verified. |
