ABSTRACT
Based on the background of studying shear stress bearing of shaft linings in the depth and thickness stratum, we carried out research and study in design of the large-scale shaft lining mechanical simulation test system. The simulation tests, namely the shear model tests on the interface of single layer shaft lining, the model tests on the coupling effect of double layer shaft linings and the mechanic characteristics of piles can be carry out. This system can simulate shear properties of the shaft lining loading up to 13MPa level pressure of the soil. A novel self-designed loading hydraulic cylinder with large diameter and hollow piston solved the problems of multi-cylinder synchronization and spatial arrangement. The flexible design of connector of test model is applicable condition in various test scheme of the thickness requirement for shaft lining. Loading method, load bearing bodies and the design of the connector of test model for simulation test provides a new way for large-scale model tests.
