| 摘 要： | 总结了1994～2000年间，作者在三峡工程永久船闸高边坡的第一期和第二期位移反分析方面的主要研究成果，包括理论与工程应用、边坡岩体变形机制及其数值模拟方法等。认为位移反分析理论研究很重要，但足由十岩体变形的非连续性，工程应用上应该加强岩体的宏观变形行为及其数值模拟方法的研究。就三峡工程的块状结构边坡而言，岩体的变形主要由松动区的变形构成，在变形分析中将松动区等效为一种弱化的线弹性材料，模拟其宏观变形行为是合适的。

| Abstract: | The main research achievements are summarized of the displacement back analysis for the permanent shiplock slope of the Three Gorges Project during its excavations of stage 1 and 2, from 1994 to 2000. The deformation mechanism and its numerical modeling of rock slopes are presented. For the back analysis of rock slope, theoretical research is important, however for engineering application, more attention should be paid to the investigation of its macro-deformation mechanism and numerical modeling technique. For the blocky rock masses of the permanent shiplock slope, their deformation is primarily composed of that of its disturbed zone, and it is feasible to model the deformation behavior of the disturbed zone by taking it as a weakened linear-elastic material. |
