The problems of environment geotechnical damage and the prediction and control of the deformations during construction by using artificial intelligent method are discussed in this article.Such soil damage and unallowable deformations are often happened under engineering construction in urban down-town areas due to construction disturbance.The factors of soil disturbance owing to various changes,as stress behavior,stress path under unloading condition in excavation,soil-void ratio,moisture content,as well as the failure of soil structures,change of soil chemical compositions,the mixture and separation of soil components,soil consolidation state,and so forth,are systematically studied.Furthermore,influence of construction disturbance as the changes of soil engineering properties above-mentioned on the soil strength,deformation,stability and bearing capacity during construction are studied theoretically and by lab-tests:sets of special experimental studies are conducted.In the other respect,for the first time soft science theory and techniques of artificial intelligence prediction and automatic control are introduced into the geotechnical field.A so-called “multi-step circulation” model of artificial neural network (ANN) method applied to predicting and forecasting the ground settlement in shield tunneling has been built,and a method of fuzzy-logic control has been used to realize the real-time and active control of deformation and displacement in construction works.

讨论了城市市区进行的各种工程活动中 ,因施工扰动引起的环境土工损伤问题及其施工变形的智能预测与控制方法 .分别对土体受施工扰动的诸因素 ,如 :对土体力学性态、开挖卸载条件下土体应力路径、土体孔隙比和含水量的变化 ,以及土体结构的破坏、土体化学组成的改变、土体成分的混合与分离和土体固结状态的变化等 ,均作了系统研究 .进而据此从理论上和实验室测试 2方面探讨了就软土工程性质的上述变化对施工过程中土体强度、变形、稳定性和承载力的影响 .另一方面 ,首次将人工智能和自动控制等软科学理论与技术引入岩土工程领域 ,采用了一种称之为“多步滚动预测”的人工神经网络模型于盾构隧道施工中地面沉降的预测和预报 ,还应用了模糊逻辑控制方法对工程施工变形位移实现了实时、主动控制
