锚锭基础岩体完整性测试与分析

Test and analysis of rock mass integrity of anchor foundation

以江西赣州赣江大桥东岸一钻孔为例,通过多种勘察手段与试验方法相结合,对大桥锚锭基础岩体裂隙、软弱夹层发育状况及裂隙胶结密实性进行了综合分析,结果表明:运用钻探方法取得RQD值对岩体进行工程质量分类结果与采用波速测试取得的岩体完整性指数分类及压水试验取得的岩体评价结果基本一致。

Taking for example the boring of east bank of Ganjiang bridge in Ganzhou,Jiangxi province,by combination of several survey means and test methods,a comprehensive analysis was made for rock crack of bridge anchor foundation, development of weak intercalation and crack cementation compactness, the result showed that the result of engineering quality classification by RQD value obtained using boring method was basically consistent with rock mass integrity index classification by adopting wave velocity testing and rock evaluation result by water pressure test.
