Study on seismic design of rehabilitated sewage pipe

本文主要研究混凝土污水管复合加固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试验，确定了其对粘结强度的影响。采用水泥砂浆材料强度参数分别对修复后的管道进行了轴向和横截面方向的抗震评估。结果表明，康复治疗效果良好，康复方法简便。

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.
