【摘要】 多点位移计及锚索测力计监测成果显示,紫坪铺引水洞进口边坡在"5.12"汶川地震后发生向坡外的变形,表面点位移增量在3.684~11.518 mm范围内,锚索荷载增量在-16.9~86.1 kN范围内,坡体整体处于稳定状态。主震对坡体变形影响最大,后期余震对坡体变形影响较小,引水洞进口边坡仍处于稳定状态。更多还原

【Abstract】 The Monitoring results by multi-point extensometer and anchor-cable dynamometer show that the entrance slope at Zipingpu Dam has deformed outwardly after the Wenchuan earthquake.The surface displacement increment is 3.684 to 11.518 mm and the anchor load increment is-16.9 to 86.1 kN,showing that the slope is basically stable.And the study reveal that the deformation has been most affected by the main shock rather,in stead of the aftershocks.更多还原
