Abstract: Cracks are common technical problems in large volume concrete construction, also is the important content of engineering quality control, based on the lock chamber side wall of mashan port lock engineering construction after partial cracks, for example, the reason of crack on the side of reinforced concrete are summarized analysis, prevention and treatment measures are put forward.
Keywords:lock side wall concrete; Crack reason; Structure length; Fracture treatment
1 概况
5 结语
马山埠船闸墙体闸室墙体净高为12.4 m,墙顶部宽度为0.5 m,底部宽度为2.0 m,伸缩缝间距为15 m,属大体积混凝土,根据工程特点,运用裂缝控制理论计算的方法,得出裂缝产生原因是由于结构长度影响所致,为下一步裂缝处理提供理论依据,同时也为类似工程提供借鉴。
