Study on seismic design of rehabilitated sewage pipe

本文主要研究污水混凝土管道复合修复方法的抗震设计方法。首先进行了填充水泥砂浆改变材料强度的室内实验，确定了它们对粘结强度的影响。采用水泥砂浆材料强度参数分别在管道轴向和截面方向对修复管道进行抗震评价。观察康复效果及康复方法。

This study focus on seismic design methodology of composite rehabilitation method for sewage concrete pipe. First we carried out the laboratory experiments of the infilling cement mortar changing material strength and made sure their effects to bounding strength. The parameters of material strength of cement mortar are used for seismic assessment of rehabilitated pipe in pipe-axis and cross-section directions, respectively. Effects of rehabilitation and rehabilitation method were shown.
