双沟水电站施工期过冰及渡凌措施

Discharge ice in construction period and discharge ice measures in Shuanggou water power station

松江河梯级双沟水电站大坝导流采取一次拦断河床,隧洞导流的方式,工程施工期间,大量冰块将通过导流洞排泄。通过模型试验及吸收有关工程成功经验,采取措施,保证了施工期导流建筑物安全行凌渡汛。

The tunnel diversion for once damming dam is adopted in the construction of Songjianghe river cascade Shuanggou water power station A large number ice is discharged through the diversion tunnel during the engineering construction. The measures are adopted to guarantee the pass ice and flood discharging in construction period according To model test and project experience.
