The multiple structure of prestressed anchor-cable frame is widely used in slope defend and landslide control. But its designing theory is far from perfection. So model test is very necessary. From the base point of anchored direction
model test needs a loading system agley. Sideling loading system design is one key tache for completing the test. By analysing the existing equipment and the characteristic of prestressed anchor-cable frame structure
a loading system is designed
including designing a rotational base for jack on
calculating for grid frame etc. The key technical issue of load direction rotational and load site shift flexible is solved. All these will have some meanings of referential guidance for others.
