一种盾构管片拆装纵向应力传递试验平台
By designing a test platform for longitudinal stress transfer during the assembly and disassembly of shield tunnel segments, the problem of insufficient research on the mechanical behavior of shield tunnel segments during the assembly stage was solved. This enabled precise simulation and control of the stress and deformation of the shield tunnel structure, thereby reducing the segment breakage rate.

AI Technical Summary
Existing technologies lack sufficient research on the mechanical behavior of tunnel segments during the assembly stage, neglecting their impact on the normal service stage of the tunnel structure. This results in a high segment breakage rate and a lack of effective longitudinal stress transfer testing methods.
A test platform for longitudinal stress transfer during the assembly and disassembly of tunnel segments was designed, comprising components such as a front baffle, a rear baffle, threaded connecting rods, rubber pads, a loading device, and a movable force-transfer baffle. The platform simulates the load and stress transfer during actual construction and obtains test data through the loading device and temporary support system.
It achieves accurate simulation of the shield tunnel segment assembly process, breaks through the constraints of traditional tests, can be reused multiple times, simplifies operation, provides detailed test data, and guides the design and construction control of shield tunnels.
