【摘要】 采用水工隧洞设计规范(SL279-2002)、(DL/T5195-2004)和断裂力学法分别对龙源口水电站发电引水隧洞山坡塌坑段衬砌结构安全进行复核.实际运行工况最不利荷载组合原型观测表明,采用断裂力学法对隧洞衬砌裂缝宽度进行验算是可行的.更多还原

【Abstract】 The lining structure safety of the mountain slope collapse section of water tunnel of Longyuankou station was rechecked by the water tunnel design code SL279-2002 and DL/T 5195-2004 and fracture mechanics.The prototype observation of the worst load combination operation duty shows that the checking computation of the practical of the lining fissure width of water tunnels is feasible by the fracture michanics.更多还原
