摘要
枕头坝一级水电站导流明渠边坡开挖规模较大,且局部存在潜在不稳定块体,对施工期安全构成威肋。为能及时了解边坡的稳定状况,为施工安全提供保证,根据现场情况,对边坡进行了位移、应力及外观变化监测,监测成果反映了施工对边坡稳定的影响,为采取安全加固措施提供了有力的基础资料,确保了边坡开挖施工的安全进行。
The excavation scale of diversion channel slope of Zhentouba Hydropower Station I is large, and the unstable blocks exist in local area, which is a threat to the safety in construction period. In order to understand the stability situation of the slope in time to ensure the construction safety, the displacement, stress of the sideslope and the variation of the appearance are moni- tored according to the situation at the construction site. The results reflect the influence of construction on the stability of slope and provide solid basic data for the reinforcement measures.
