中文摘要：
根据地下工程非线性位移反分析的特点，建立起基于地下洞室收敛位移量测结果的反分析模型；针对一般退火演化算法优化效率低的问题，综合运用遗传算法、模拟退火算法和非线性有限元分析手段，并引进自适应的思想，建立了基于自适应退火演化算法的地下工程非线性位移反分析的新方法和理论，在探讨其应用方法与实施过程的基础上，开发了相应的计算分析程序。模拟分析表明，理论计算结果与模拟结果吻合良好，该方法可以满足工程要求。
英文摘要：
Firstly, according to practical features of nonlinear displacement back analysis for underground structure, the model of back analysis which is based on convergent measuring data of displacements in underground tunnel, is established. Secondly, aiming at low calculating efficiency of general annealing algorithm, a new way or theory of nonlinear displacement back analysis in underground engineering which is based on adaptive hybrid genetic-simulated annealing algorithm, has been set up by combination of genetic algorithm with annealing algorithm together with finite element method and by introducing the idea of adaptation. And then, the relevant analytic software is developed based on studying both application and execution of this method. Finally, simulation analysis is carried out; and it is indicated that the theoretical results tally well with practical ones; and this method can meet the requirements for practical engineering.
