Abstract

The stability of a large-scale cut slope subjected to staged reinforcement has been investigated using field monitoring and slope modeling. The slope reinforcements used include piling, nailing, and anchoring and these were installed in the upper and lower parts of the slope in six stages. To analyze changes in the stability of the reinforced slope during these stages, an instrumentation system was installed and monitored carefully. It was observed that the safety factor of the slope, and the deflection and bending stresses of the stabilizing piles varied significantly as the reinforcements work processed. The most critical stage was observed to occur during the soil-nailing stage. The measured deflection of piles at the pile head is smaller than that of the analytical values. The result comes from the influence of the restrained effect of horizontal deflection caused by both anchoring in the upper part and concrete capping in the lower part. The safety factor of the slope is gradually increased, subjected to reinforcement stages and satisfied with the allowable standard values in both dry and rainy conditions.
