| 摘 要： | 土石坝的安全监测包括两个部分,一是关于应力的监测,主要是孔隙水压力的监测；二是变形的监测,包括地表沉降、地基深层分层沉降、坝肩水平位移等.实际工程表明,土石坝在填筑施工中出现安全问题时,超孔隙水压力与坝肩水平位移会明显偏大,结合地表沉降与坝基深层位移监测结果能够对坝体施工安全有效预警.为研究土石坝坝体与软弱地基的沉降、...

| Abstract: | The safety monitoring for earth rock dam consists of two parts.One is the monitoring of stress which is mainly about pore water pressure monitoring.The other is about deformation monitoring including observation of surface subsidence, deep layer ground subsidence and horizontal displacement on the abutment of the dam.The actual project shows that the water pressure and the horizontal displacement on the abutment of the dam will be significantly larger than normal status before the dam is in danger.It can gi... |
