摘要
用有限差分法计算了三峡永久船闸闸室混凝土底板的温度场 ,考虑了分层浇筑的影响以及水管初期通水冷却和水管中后期通水冷却的效果 .对其应力场进行了分析 .推荐了比较有效的温控措施 .
Temperatures are calculated for the ship lock concrete base slab in the Changjiang Gorges by use of finite difference method. The effects of layered construction and pipe cooling in initial and later stages are taken into account. Thermal stresses are analyzed and a comparatively effective temperature control measure is recommended.
