Abstract
Previous studies on the construction of lock-head allow to state that not only provide the means to reduce the stress, but more accurately reflect the actual force of the structure, which are given but there is no effect on the timing of the commissure analysis for the joint project.Based on the design of Xiangjiang River in Changsha integrated hub project, this paper propose the lock structure and layout of the program, in full consideration of the lock complex foundation condition, complex structure, temperature stress and other factors.In this paper, numerical simulation is used to simulate a variety of reasonable construction sequence and construction process, to analysis the characteristics of the stress of the bottom plate of the sluice, the settlement of the foundation and anti-force distribution features. And then discusses the overall stress characteristics and working mechanism of the first structure of the lower gate. On the basis of this, the reasonable construction sequence and structure optimization scheme are put forward.
