疏排水
1.
Field measurements were carried out in order to obtain the variation laws of the strains of the shaft lining during drainage and grouting.
为掌握冲积层疏排水及注浆加固地层过程中井壁的变形规律,开展井壁变形实测研究,获得如下规律:在冲积层疏排水过程中,井壁竖向受压,竖向压应变随疏水层水压下降而增大,与此同时井壁环向因泊松效应产生相对拉应变;相对于每次注浆前的初始状态,在注浆过程中井壁内缘有两个水平切向受拉区和两个水平切向受压区,受拉区或受压区的圆心角为90°左右,距注浆点最近和最远的两个区域受拉;注浆使井筒周围土层抬升,使井壁在竖向相对受拉,缓释了井壁内的压应力。
