The road cutting rock slope above the Dongmenguan tunnel in Xuanen sector of Hubei Provincial 209 highway

is a typical loosen structure one. According to characteristics of engineering geological

hydrogeological

structure of rock mass and prior symptom of deformation and failure of the slope

potential types of slope failure are identified; and un-equilibrium pushing method commended by present criterion is used to calculate the slope stability and to process treatment design. During remediation for the slopes of loose material

general treatment techniques always bring many problems such as the extrusion of soil above top of pile

the extrusion of soil between piles

and the decay of anchoring forces in cable bolts; so techniques relating to cutting

anchoring

structure beam and retaining wall are proposed to substitute techniques caused problems. A new method about solving the problems of analyzing and remedying loosen structure road cutting rock slope is presented.
