Analysis of Protection Engineering for High Slope in Western Henan Province

Abstract:

Multistage discharge gentle slope combined with wide platform was adopted in the protection for high slope of highway in loess area, but vertical slope was often adopted at construction engineering of high slope as there was no enough site space for step-slope under the construction of urbanization in the western loess region of Henan province. A typical loess high slope in Lingbao city was taken to discuss the prevention measures for upright loess high slope. Design parameters for slope protection was given in detail, approach on the control plan for deformation has both excavation slope of 35m high and fill slope of 30m high. While reinforcement scheme of anchor cable plus stiffened-cylindrical was used in slope protection, the reinforced retaining wall was used to support the filling slope, in addition, loess slope management must be prepared to slope drainage design and construction.
