针对在航道整治工程中对整治建筑物的安全性没有具体的定量化判别方法,在总结前人研究的基础上,通过抛石丁坝清水冲刷试验,提出一种以坝体水毁体积比来快速判别丁坝安全性的方法.由于丁坝结构复杂,影响坝体水毁的不确定因素众多,因此采用量纲分析法建立抛石丁坝水毁体积比计算公式.该式将抛石丁坝水毁体积与其影响因素直接联系起来,能够定量反映水毁因素与水毁程度之间的关系,从回归方程的计算结果来看,计算值和试验数据吻合较好,可为实际工程设计和维护提供参考依据.
In view of the waterway regulation project on the safety of remediation of buildings without quantitative methods, based on the previous studies, based on the scouring test by rubble dam water, put forward a dam to the volume ratio of water destroyed quickly Because of the complicated structure of the dams, there are many uncertain factors affecting the dam damage, so the formula for calculating the volume ratio of the destroyed dams is established by using the dimensional analysis method. The direct relationship between the influencing factors can quantitatively reflect the relationship between the water damage factors and the degree of water damage. According to the calculation results of the regression equation, the calculated values agree well with the experimental data, which can provide reference for the actual project design and maintenance.
