Taking Xiajia continent, which was seriously damaged in Haiyuan earthquake in 1920, as the research object, the basic physical property test, dynamic triaxial test and synthetic seismic data of loess layer were carried out.
The physical and mechanical test of landslide mainly includes density test (wet soil mass, wet density, dry density and average wet density), water content test (water mass, dry soil mass and water content, etc.), specific gravity test (Pycnometer, total mass of liquid and soil and mass of liquid with the same volume as dry soil), liquid plastic limit test (plastic limit, plastic index and liquid index), and the data are stored in Excel.
Xiajia continent, which was seriously damaged in the Haiyuan earthquake in 1920, was selected as the research object, and loess samples of different layers were collected manually.
Carry out indoor physical and mechanical tests and dynamic triaxial tests of loess according to the requirements of geotechnical test method standard GBT 50123-2019, calculate the corresponding physical and mechanical parameters, and summarize the parallel test data; The design seismic response spectrum is based on the standard response spectrum parameters given in the code for seismic design of buildings and practical engineering experience, and then the required response spectrum is obtained through multiple superposition calculations.
Operations were conducted in accordance with the standard specifications of "Standard for geotechnical testing method (GB/T 50123-2019)" and "Code for Seismic Design of Buildings," and the data quality is good.
