基于 HDBSCAN 算法的岩体结构面产状识别及分组方法.

Publication Type: Academic Journal

Source(s): Journal of Northeastern University (Natural Science). Jun2022, Vol. 43 Issue 6, p888-896. 9p.

Abstract: 精准获取岩体结构面的产状信息是进行岩体稳定性分析工作的首要和关键步骤.针对基本 DBSCAN 算法在处理点云数据时存在聚类判据不足、参数敏感性较强等问题,提出了基于点云附加属性扩展聚类判据的 HDBSCAN 算法,旨在提高算法聚类的准确性及鲁棒性.同时,基于点云的颜色及密度属性实现了对自然状态下非全裸露岩体研究区域的分割和提取,减少非岩体结构面点云对结构面产状识别和分组的影响.将该方法应用于大石洞灰岩矿某一典型覆土岩坡,结果表明:该方法能够有效地剔除非目标点云数据,同时结构面产状提取和优势分组结果令...

Numerical and Larg-Scale Laboratory Study of Rock Column Groups in Sandy Soil Behavior Improvement.

Publication Type: Academic Journal

Source(s): Advances in Civil Engineering. 8/1/2022, p1-11. 11p.

Abstract: The use of stone columns as one of the effective methods in improving soil behavior can increase soil bearing capacity. One of the common methods in improving poor soil is the use of stone columns. Stone columns are considered one of the suitable optio...

Selected Liver Markers in Predicting the Severity of Organophosphate and Carbamate Poisoning.
