| 英文摘要 | For high cutting slopes, it is quite necessary to set pre-reinforced structures before the slope excavation to avoid the slope failure during the excavating. In this paper, the multi-wedge translation mechanism is used to analyze the stability of high cutting slopes pre-reinforced with piles. First, the multivariate functions are established to calculate safety factor for the slope during the excavating. Based on the safety factor of the slope during the excavating process, it can be determined that whether the slope need set the pre-reinforced piles before excavating. If need, the most significant factor for pre-reinforced pile design is the stabilising force. Then the expressions are derived to calculate the stabilising force provided by the pre-reinforced piles to increase the safety factor to assure the high cutting slope is stable. At last, an example is taken to illustrate the method proposed in this study. The result shows that the safety factor for the slope is change with the excavating. The stabilising force is influenced by the location of pre-reinforced piles, excavation distance and slope angle. The most suitable location of pre-reinforced piles within the high cutting slope also had been determined. |
