Taking the severely damaged Haonei area during the 1920 Haiyuan earthquake as the research object, basic physical property tests, dynamic triaxial tests, and synthetic seismic data for loess layers were conducted.
The physical and mechanical tests for the landslide mainly included density tests (wet soil mass, wet density, dry density, and average wet density, etc.), moisture content tests (water mass, dry soil mass, and moisture content, etc.), specific gravity tests (specific gravity bottle, total mass of liquid and soil, and mass of liquid with the same volume as dry soil), and liquid-plastic limit tests (plastic limit, plasticity index, and liquidity index). The data was stored in Excel format.
Selecting the severely damaged Xiajiadalu area during the 1920 Haiyuan earthquake as the research object, loess samples from different horizons were manually collected.
In accordance with the requirements of the "Standard for geotechnical testing method (GBT 50123-2019)," laboratory physical and mechanical tests and dynamic triaxial tests were conducted on loess, and corresponding physical and mechanical parameters were calculated. Parallel test data was summarized. The design earthquake response spectrum was determined by combining the "Code for Seismic Design of Buildings" and practical engineering experience to provide standard response spectrum parameters, which were then used to obtain the required response spectrum through multiple superposition calculations.
Operations were conducted in accordance with the "Standard for geotechnical testing method (GBT 50123-2019)" and the "Code for Seismic Design of Buildings," ensuring high-quality data.
