The invention discloses a device and method for monitoring the stability of a rock-soil body under dry-wet cycle and earthquake coupling. The device comprises a bearing body, a vibration simulation device, a temperature simulation device, a rainfall simulation device and a control device, wherein the bearing body is used for bearing a to-be-monitored rock-soil body; a vibration assembly of the vibration simulation device is connected with the bearing body and used for vibrating the rock-soil body; a heating assembly of the temperature simulation device is used for changing the environment temperature of the rock-soil body; the rainfall simulation device is arranged above the vibration simulation device and the rock-soil body and used for changing the humidity of the rock-soil body; and thecontrol device is used for communicating with the vibration simulation device, the temperature simulation device and the rainfall simulation device. The device provided by the invention integrates rainfall, dry-wet cycle and earthquake action, can accurately simulate artificial rainfall, dry-wet cycle, earthquake action and rock-soil body stability test under coupling of any action, and providesreliable test parameters for researching the stability of the rock-soil body under extremely severe environmental conditions.
Description
technical field [0001] The invention relates to the field of rock-soil mass testing, in particular to a device and method for monitoring the stability of rock-soil mass under dry-wet cycle and seismic coupling. Background technique [0002] At present, the analysis of slope stability in the field of geotechnical engineering mainly focuses on the study of high slopes, hydrological environment, rainfall and rainwater seepage, construction excavation and filling conditions, and earthquakes. For dry-wet cycles, rainfall, earthquakes, There are very few studies on slope stability under the coupling of various extreme harsh environments such as snow, and the existing research on the coupling of multiple harsh environments is mainly based on the numerical model analysis of various calculation software, lacking corresponding test devices and methods. verify. Contents of the invention [0003] In order to solve at least one of the above technical problems, the embodiments of this ...
