混凝土弹性模量的发展不仅依赖于龄期，也依赖于自身温度。大体积混凝土由于水化温升和周围环境的影响，各处的温度场一般并不均匀，这就导致了同一龄期结构各部位混凝土弹性模量的差异。现有的弹性模量计算模型多不能对这种差异进行描述，因此，本文在混凝土开裂全过程仿真试验机的基础上，建立考虑自身温度和温度历程的基于等效龄期的混凝土弹性模量计算优化模型", "ds_acq_start_time": "2015-01-01 00:00:00", "ds_acq_end_time": "2021-12-30 00:00:00", "ds_acq_place": "北京", "ds_acq_lon_east": 102.60666666666665, "ds_acq_lat_south": 26.336944444444445, "ds_acq_lon_west": 102.60111111111111, "ds_acq_lat_north": 26.346944444444443, "ds_acq_alt_low": null, "ds_acq_alt_high": null, "ds_share_type": "login-access", "ds_total_size": 15709514, "ds_files_count": 4, "ds_format": "*.xls", "ds_space_res": null, "ds_time_res": "", "ds_coordinate": "无", "ds_projection": "", "ds_thumbnail": "9d1e5c49-4f8f-4bbd-9ad0-3ba9d7dbee0d.png", "ds_thumb_from": 0, "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": 0, "publish_time": "2025-05-29 18:14:00", "last_updated": "2025-05-29 18:14:00", "protected": false, "protected_to": null, "lang": "zh", "cstr": "11738.11.NCDC.NHRI_DAM.DB6853.2025", "i18n": { "en": { "title": "The dataset of temperature stress testing machine for the entire process of concrete in Wudongde High Arch Dam", "ds_format": "*.xls", "ds_source": "
The experimental data mainly combines the actual on-site measurement of concrete temperature in engineering, and simulates the entire process of the temperature tracking system of the temperature stress testing machine through early age concrete testing.

The development of the elastic modulus of concrete depends not only on its age, but also on its own temperature. Due to the influence of hydration temperature rise and surrounding environment, the temperature field of large volume concrete is generally uneven, which leads to differences in the elastic modulus of concrete in different parts of the same age structure. Most existing elastic modulus calculation models cannot describe this difference. Therefore, based on the simulation test machine for the entire process of concrete cracking, this paper establishes an optimization model for calculating the elastic modulus of concrete based on equivalent age, considering its own temperature and temperature history", "ds_ref_way": "", "ds_abstract": "
Based on the simulation testing machine for the entire process of concrete cracking, early age tests and model construction of concrete were conducted under different cooling rates and constraint conditions to explore the development process of elastic modulus of concrete in different parts of the structure for a more comprehensive description.
