【摘要】 针对某矿地层注浆治理立井井壁破裂工程期间获得的大量实测数据,分析处理得出相应无量纲影响因子以及任意注浆段注浆活动对井壁中任意监测点竖向应变改变量的影响关系式。结果表明,注浆孔位与监测点的空间相对位置、注浆压力及注浆量对监测点的竖向应变改变量的影响均属非线性,其中竖向相对位置影响较为显著。更多还原

【Abstract】 A great amount of monitoring data were obtained during the grouting reinforcement process in vertical shaft;and then several specific non-dimensional impact fatcors were educed from these original test data.Using nonlinear least square approximation method,the relation between the vertical strain change of arbitrary position on the shaft lining and the given grouting phase was reached.The analysis result shows that not only the relative space location between grouting place and monitoring point,but also the grouting pressure and injected amount affects this vertical strain change nonlinearly;and that vertical relative location has the more prominent affection.更多还原
