| 摘 要： | 通过对牵引式滑坡发展过程的分析，着重说明牵引式滑坡自下而上规模不断扩大的特性。牵引式滑坡整治分被动加固与主动加固：被动加固存在着滑面抗剪强度下降、滑动范围扩大、加固力增大等问题，并造成较大的工程损失和环境资源破坏；主动加固能有效利用潜在滑动面的固有强度，减少工程造价。在被动加固时，应考虑牵引式滑坡的发展过程，对最初滑体采用有效加固、后牵引滑体采用加固补偿的原则。

| Abstract: | Base on the analysis of the process of retrogressive landslide,it shows that the characteristics of retrogressive landslide are developed from underside to upside;and its scope becomes larger and larger.The treatment to retrogressive landslide is passive and active reinforcements,but some problems will be brought in by passive reinforcement,such as the decline of shear strength of sliding surface,the expanse of sliding range,the increase of passive reinforcement force,the loss of project budget and the dest... |
