摘要通过各设计阶段对溪洛渡特高拱坝岩石工程关键技术问题的不断深入研究，使得拱坝体型和结构设计很好地适应坝址地形地质条件；面对河床坝段基础地质条件的变化，通过建基面扩大开挖和上下游贴角设计，使得拱坝和基础相互协调，改善坝体和地基应力条件。三维地质力学模型试验和有限元分析表明，溪洛渡特高拱坝和基础具有良好的工作性态。监测成果表明，拱坝和基础实际工作性态符合规律。基于全寿命周期理论的溪洛渡“数字大坝”的建设与实践，为施工过程控制和决策提供了有力支持，进一步保证了拱坝在施工期和运行期各阶段的工作性态满足设计要求，保障了拱坝的安全可靠。

Abstract：In each design phase，thorough studies were conducted to explore the key technical issues of rock engineering for the superhigh arch dam of Xiluodu hydropower project，allowing the physical shape and structural design of the arch dam to fit the geological conditions of the dam site. In view of changes in the geological conditions at the foundation of the dam on the riverbed，the designs of extending foundation surface excavation and dovetailing the dam body and foundation rock on both upstream and downstream sides were introduced，allowing the arch dam and foundation to fit each other and improving the stress conditions of the dam body and foundation. 3D geomechanics model test and finite element analysis results indicate that the Xiluodu superhigh arch dam and its foundation are in good conditions both in construction and operation periods. The monitoring data show that the behaviors of dam and foundation correspond with regular pattern. The“digital dam” initiative for the Xiluodu project，which is based on the theory of total life cycle，has lent strong support to construction process control and decision-making；this ensures all work conditions in the construction and operation stages meet design requirements，so as to assure the safety and reliability of the arch dam.
