| 英文摘要 | This study was undertaken in order to analyze the dynamic stability of the slope supported by frame structures with prestressed anchors under earthquake. Taking a mid-span column unit as the object, the dynamic earth pressure on the supporting structures by considering the slope acceleration amplification effect was analyzed, then the supporting structures were simplified, and the prestressed anchors were treated as the dynamic earth pressure on the supporting structure and the inertial force of the supporting structures in the same direction, so the simplified dynamic response model of supporting structure was established. The force method was used to solve the axial force of the anchors. Then the source of the axial force of the anchors was analyzed and range of anchoring area of anchors was solved. The horizontal soil strip was taken as the horizontal soil layer within the range of anchoring area of anchors. The vertical soil strip was taken as the vertical soil layer corresponding to the sliding surface of the horizontal soil strip. According to the failure mode of the slip surface of the soil slope that a dynamic stability model of the slope was established, by considering the influence of the vertical component of seismic action, on the basis of quasi-static method, the horizontal slice method and the vertical slice method were used to derive the slope dynamic stability coefficient calculation equation. Finally, using the algorithm in this paper and the finite element software Geo-Studio, the actual engineering examples were calculated. The results show that the algorithm in this paper has a certain degree of reliability, and can be used for this kind of engineering design and provide corresponding reference for the dynamic stability research of frame structures with prestressed anchors. |
