Abstract: Spillway is widely used. Due to temperature stress, uneven settlement of foundation, and the impact of operating environment and climate change, a certain degree of compression damage would occur on the spillway pier concrete, resulting in gnawing edge, collapsed angle and concrete cracks, which directly affect the safety and stability of the pier. Taking the Akosombo dam in Ghana as an example, this paper expounds the application of elastic epoxy mortar in repairing the pier structural joints, for reference.

Key words: concrete, structural joint, elastic epoxy mortar

摘要： 水工混凝土建筑物中，溢洪道的应用很广泛。由于温度应力、地基不均匀沉陷，同时受运行环境、气候变化影响，溢洪道闸墩混凝土会存在一定程度的挤压破坏，导致产生啃边、崩角、混凝土裂缝，直接影响闸墩安全稳定。以西非加纳Akosombo大坝为例，介绍弹性环氧砂浆在闸墩结构缝修补中的应用，以期为类似工程提供参考。
