Title:
UPWARD EARTH PRESSURE SHIELD EXCAVATION FACE STABILITY TEST APPARATUS AND USE METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/226249
Kind Code:
A1
Abstract:
An upward earth pressure shield excavation face stability test apparatus and a use method thereof. The apparatus comprises a model main body structure, a propulsion control system, a data acquisition system, and a water level control system, the model main body structure comprising a model box (14), a horizontal tunnel model (11), and an upward shield model (21). The use method comprises a test preparation stage, an excavation face movement stage and a data processing stage. The apparatus and method can be used for studying a destabilization process of an upward shield excavation face, and observing ground surface displacement, changes of excavation face soil pressure, excavation face supporting force, excavation face pore water pressure and horizontal tunnel strain, and changes of a displacement field of a soil body above the excavation face during the destabilization process as well as rules of changing of various data during the destabilization process, and meanwhile, by means of adjusting test conditions or test parameters, working conditions can be changed so as to study effects of different working conditions on destabilization of an excavation face.
