Engineering, Tongji University, Shanghai 200092, China;5. East China Architecture Design Institute, Shanghai 200002, China)Abstract:Long-term settlements for underground structures, such as tunnels and pipelines, are generally observed after the completion of construction in soft clay. The soil consolidation characteristic has great influences on the long-term deformation for underground......
; Technology,Changsha 410114, China Central South University Press and Springer-Verlag GmbH Germany, part of Springer Nature 2017 Abstract: Long-term load and flexural failure experiments are carried out on two prestressed concrete (PC) simply supported box girders. In the long-term load experiment, girder-1 (G1) is in an elastic state, while girder-2 (G2) is in a cracking state. To investigate......
-term self-learning and long-term self-learning models was made. The point in the short-term self-learning is how to premise the smooth modulus in the method of exponential smoothing. A multi-variable.... In the aspect of long-term self-learning, the main mission is the launch conditions of the self-learning, and how to select the strategy of learning coefficient about the first piece of steel after changing......
