中文摘要：

水库滑坡（变形体）防治工程研究是三峡库区地质灾害防治工作的重心和难，点问题。依据抗滑桩优化设计工作中各重要环节的工作内容，对滑带土强度参数的选择，抗滑桩位置和设计推力、抗滑桩间距、锚固段长度的确定等影响抗滑桩优化设计的关键技术问题进行了讨论，提出解决这些问题的方法。

英文摘要：

The improvement engineering of landslide （deformation slope） is important in the geological hazard control in the Three Gorges Reservoir region. Based on the content of each important stage of the optimum design on anti-slide pile, this paper discusses several key problems for optimum design on anti-slide pile, such as the choice of intensity parameter of the sliding zone, confirming the pile position, pushing force design, the pile interval and the anchoring depth, and then presents some methods for solution.
