| 摘 要： | 温度应力是造成混凝土重力坝坝体裂缝的主要原因,而对扩建工程,由于原坝体温度场、材料弹性模量和徐变等力学性能与新浇坝体的差异,使温度应力造成的各种不利情况更严重、更复杂.因此,采取有效的温控措施是十分必要的.本文介绍了英那河水库重力坝加高采取的温度应力控制措施,实践证明效果良好.

| Abstract: | Temperature stress is the main reason for cracks on concrete gravity dams. In heightening, due to the difference of the temperature field, material elastic modulus and creep between the new and old dam body,the abverse conditions caused by temperature stress would be more serious and complicated. So, it is necessary to take effective measures to control the temperature. In the paper, the temperature control measures were introduced and the measures were proved effective. |
