摘　　要：文中旨在研究复杂地质条件下重力坝设计方案的优化问题,提出了一种基于APDL参数化建模与优化搜索以及以ANSYS作为强大有限元求解器的综合优化分析方法。该方法利用APDL构建重力坝的参数化有限元模型,能够灵活调整坝体尺寸、材料属性及地基处理方案等设计参数。在复杂地质条件(如不同岩层分布、断层、软弱夹层等)下,通过优化算法以最小化坝体应力、提高结构稳定性、降低建造成本等为优化目标。本研究不仅为复杂地质条件下的重力坝设计提供了一种高效、系统的优化方法,也为类似工程问题的解决方案提供了有益参考。This article aims to study the optimization problem of gravity dam design schemes under complex geological conditions,and proposes a comprehensive optimization analysis method based on APDL parametric modeling and optimization search,as well as ANSYS as a powerful finite element solver.This method utilizes APDL to construct a parameterized finite element model of a gravity dam,which can flexibly adjust design parameters such as dam body size,material properties,and foundation treatment plans.Under complex geological conditions such as different rock formations,faults,weak interlayers,etc.,optimization algorithms are used to minimize dam stress,improve structural stability,and reduce construction costs as optimization objectives.This article not only provides an efficient and systematic optimization method for the design of gravity dams under complex geological conditions,but also provides useful references for solving similar engineering problems.
