Abstract：
Slope excavation, column-anchor retaining structure, pre-stressed anchor cable pile are designed for the deep pit support in earth-rock dualistic stratum. Slope top horizontal and vertical displacement，soil deep displacement, anchor rod(or anchor cable) internal force, retaining pile(or retaining column) rebar internal force are monitored in construction. The monitoring data demonstrate supporting effect is satisfactory because the pit is stable in construction.
