基于FEM-DDA连续非连续开裂扩展技术对高混凝土坝数值模型的病变灾变损伤过程的分析计算是提出高混凝土坝病变灾变判别标准的重要理论支撑。该数据集为高混凝土坝病变灾变模拟技术下的研究，研究不同高程顺河向位移与谷幅变形量值关系曲线，y轴为顺河向变形（mm），x轴为谷幅收缩量值（mm）。", "ds_source": "

当谷幅收缩变形量值为300mm时，900m高程特征点的顺河向变形存在轻微的减少，此时开裂损伤深度基本贯穿整个上下游面，此时大坝可能已经发生病变灾变破坏。", "ds_acq_start_time": "2025-01-01 00:00:00", "ds_acq_end_time": "2025-05-25 00:00:00", "ds_acq_place": "乌东德水电站", "ds_acq_lon_east": 102.60888888888888, "ds_acq_lat_south": 26.336944444444445, "ds_acq_lon_west": 102.6111111111111, "ds_acq_lat_north": 26.346944444444443, "ds_acq_alt_low": null, "ds_acq_alt_high": null, "ds_share_type": "login-access", "ds_total_size": 68680, "ds_files_count": 2, "ds_format": "*.xlsx", "ds_space_res": null, "ds_time_res": "", "ds_coordinate": "无", "ds_projection": "", "ds_thumbnail": "ab2ae637-f850-4fab-b9fa-26e940869e39.png", "ds_thumb_from": 2, "ds_ref_way": "", "paper_ref_way": "", "ds_ref_instruction": "", "ds_from_station": null, "organization_id": "973f338d-7fd4-4c6f-aab1-44a5c242d419", "ds_serv_man": "李红星", "ds_serv_phone": "0931-4967592", "ds_serv_mail": "ncdc@lzb.ac.cn", "doi_value": "", "subject_codes": [ "410" ], "quality_level": 3, "publish_time": "2025-05-29 18:13:54", "last_updated": "2025-05-29 18:13:54", "protected": false, "protected_to": null, "lang": "zh", "cstr": "11738.11.NCDC.NHRI_DAM.DB6851.2025", "i18n": { "en": { "title": "Data set of relationship curves between river displacement and valley amplitude deformation at different elevations", "ds_format": "*.xlsx", "ds_source": "

When the value of valley contraction deformation is 300mm, there is a slight reduction in the deformation along the river direction at the 900m elevation feature point. At this time, the depth of cracking damage basically runs through the entire upstream and downstream surfaces, and the dam may have already undergone pathological and catastrophic damage.", "ds_ref_way": "", "ds_abstract": "
The analysis and calculation of the damage process caused by pathological disasters in the numerical model of high concrete dams based on FEM-DDA continuous discontinuous cracking propagation technology is an important theoretical support for proposing the criteria for identifying pathological disasters in high concrete dams. This dataset is a study on the simulation technology of high concrete dam damage disasters, investigating the relationship curve between displacement along the river direction and valley amplitude deformation at different elevations. The y-axis represents the deformation along the river direction (mm), and the x-axis represents the valley amplitude shrinkage value (mm).
