Cause Analysis and Evaluation of the Crack on the Crest of a Plain Reservoir
The uneven settlement of the dam after the capacity expansion of a plain reservoir leads to different degrees of cracks on the crest of the dam section,which affects the normal operation of the dam.In order to evaluate whether the crack affects the operation safety of the reservoir,the causes of the crack on the crest of the dam are analyzed and evaluated through on-site inspection,geological investigation,and consulting the design,construction and operation management data.The results show that the cracks at the top of the dam section are mainly caused by the uneven settlement of the dam foundation and the poor density of the dam body.Although there is no short-term rapid subsidence at the current situation of the box dam,the risk that the continuous development of the cracks will endanger the stability of the dam slope and destroy the integrity of the seepage prevention.It's suggested to do the curtain for strengthening to the box dam.
