In view of the temperature and temperature stress of mass concrete of lock’s hydraulic structure,this paper carries out the whole-course automatic analysis through the secondary development of the finite element software ANSYS, design of visual parameter input interface by the VB language, and combining with the APDL language of the software to simplify the complicated whole-course simulation analysis and enhance its efficiency and practicability, and to better solve practical engineering problems. The paper also involves calculation and analysis of the temperature and temperature stress of a typical docking lock chamber to provide references for technicians.
