Title:
DEFORMABLE LARGE-SIZED SOIL CONTAINER STRUCTURE FOR TRUE TRIAXIAL TESTING IN SOIL ENGINEERING
Document Type and Number:
WIPO Patent Application WO/2020/244581
Kind Code:
A1
Abstract:
A deformable large-sized soil container structure for true triaxial testing in soil engineering, primarily used for true triaxial large-sized model testing in soil engineering. The structure comprises an operation platform (1), lateral loading plates (7), a normal-direction loading plate (10), and a base plate (2). The main body of a soil container is formed from four upright lateral loading plates (7) which are used to bear horizontal loads. Adjacent lateral loading plates (7) are connected via a lateral guide device (6). The normal-direction loading plate (10) is disposed above the main body of the soil container. A normal-direction constraining frame (9) is provided at an outer periphery of the normal-direction loading plate (10). A normal-direction loading plate guide device (12) is further disposed on the normal-direction loading plate (10). The invention employs the combination of the normal-direction constraining frame (9) and the normal-direction loading plate (10) to achieve restricted deformation of the soil container in a vertical direction, thereby ensuring right-angled connections between plates. The invention further adopts a logical design including a lateral loading device (4), the lateral guide device (6), and a lateral sliding device (5) to achieve free deformation of the soil container within restrictions and real-time coaxial loading in a horizontal direction, thereby ensuring overall operational safety and reliability of a true triaxial testing system, and providing significant financial and practical value.
