Abstract

Abstract: By analyzing the causes of quality accidents of slope engineering, it is discovered some main problems in design, such as probleMabout selection scheme of retaining structure, probleMabout base of design, probleMabout destructive model of slope and calculation method, probleMabout the value of theoretical destructive angle of the rock slope, probleMabout calculation of internal force and combination, and probleMabout treatment of structure and construction. At the same time, these problems in design reveal that a thorough and meticulous analysis needs to be made in design in various aspects, which can avoid some quality accidents due to the improper design. Moreover, this is also very important to reduce the geotechnical engineering disaster.

Key words: slope, quality, accident, design reason, disaster

摘要： ：拟静力法和动力有限元安全系数时程分析法在评价地震动作川下边坡的稳定性时具有一定的局限性，拟静力法在分析边坡地震稳定性时无法反映边坡的动力特性，动力有限元安全系数时程分析法将动力问题转化成静力问题，只是在一定程度上考虑了边坡的动力响应。j拟静力法和动力有限元时程分析法相比，完全动力分析法在应用强度折减法的基础上考虑边坡的扣一剪破坏，并且能够比较全面的反映岩土体的动力特性。通过算例分析证明 r完全动力分析法在评价地震动作用下边坡的稳定性是可行的，这为边坡地震动作用下的安全系数求解提供了一种较为有效的途径．．
