摘要
对新开沱河节制闸墩墙的裂缝进行了检测,分析认为温度应力及收缩应力是裂缝产生的主要原因。对裂缝进行了注浆处理,消除了裂缝对结构耐久性的不利影响。
The concrete cracks in sluice pier wall of New Kaituo River were checked, and it was found that the temperature stress and shrink stress are the main reasons for cracks formation. The cracks were treated with slurry injection, and the adverse influence of cracks on structure endurance was avoided.
