A new type anchor cable with double anchor is developed to explore endurable and anchoring effect of anchorage system in the slope of high embankment and deep cut slope. Based on its structural design

anchorage mechanism and structural characteristics

the stress model and calculation method are analyzed. The endurable and anchoring effect of the double anchor cable anchorage are analyzed through indoors contrast analysis experiments. Experimental results indicate that: (1) The outer anchorage section played an effective and dual-function anchorage role. (2) Double anchoring section system is able to effectively avoid the prestress loss caused by anchoring failure (3) Compared to the traditional cable

the new type anchorage system is able to realize self-locking function

and demonstrated characteristics of high safety

reliability. Accidents by sudden catastrophic failure of anchor cable can be effectively avoided. Thus

high effectiveness-cost ratio is realized in the long term. (4) The engineering cases show that

the failure of outside anchor head and prestress loss of free section can be effectively inhibited

when the outside solid length of Carboniferous rocks formation sandstone

mudstone and dark gray limestone

with interbedded strata are not less than 8 m

These experimental results can be used as a valuable reference for the correct analysis of the mechanism and engineering design of the new double anchor cable.
