某采煤沉陷区综合治理工程基桩试验研究

Research on comprehensive treatment of foundation pile experiments in some mining subsidence areas

通过某采煤沉陷区综合治理工程住宅楼人工挖孔钢筋混凝土嵌岩端承桩设计,采用岩基载荷试验方法确定了桩端持力层岩石饱和单桩抗压强度标准值和采用动力检测法检测了工程桩的桩身质量,结果表明人工挖孔钢筋混凝土嵌岩端承桩在处理某采煤沉陷区效果较好。

According to the design for the rock-socketed part＇s bearing piles with manual digging hole reinforced concrete in the comprehensive treatment of the residential buildings in some mining subsidence areas,the paper adopts the rock foundation loading experiment to identify the standard value of the saturated single pile strength in bearing course at pile ends and uses the dynamic detection method to test the quality of the engineering piles,and proves the effect of using rock-socketed part＇s bearing piles with manual digging hole reinforced concrete in treating the mining subsidence areas is better.
