Problems solved by technology

The test strain of the resonant column test is small, which can provide the index of small strain for the analysis of the ground dynamic response; the dynamic torsional shear instrument can simulate the stress condition on site, and is an ideal instrument for measuring the dynamic index. However, the instrument has a complex structure and is difficult to operate. Can only be used as disturbed soil

Description

technical field [0001] The invention relates to indoor model test technology of geotechnical engineering, in particular to a test method and device for simulating dynamic and static loads. Background technique [0002] Dynamic and static loads often exist in foundation deformation and structural stability analysis, such as: gravity load, earthquake load, wind load and explosion on high-rise buildings, hydrodynamic pressure on dams, waves on coasts and offshore oil production The impact of the platform, the impact of vehicles on road operations, etc. The properties of soil and structures have changed greatly under the action of dynamic and static loads, so the research on the properties of soil and structures under the action of dynamic and static loads is an important work in the field of geotechnical engineering. At present, there are not many studies on the response characteristics of soil and structures to dynamic and static loads. [0003] According to the dynamic load...
