HDPE双壁波纹管-CIPP内衬复合结构受力特性研究OA北大核心CSTPCD
Bearing characteristics of HDPE double-wall corrugated pipe-CIPP lining composite structure
原位固化法(CIPP)可用于修复高密度聚乙烯(HDPE)双壁波纹排水管,但目前没有合适的模型来量化评估修复后整体结构的承载特性,修复设计无据可依.为此,首先基于叠合曲梁模型和复合曲梁模型对修复结构整体的受力特性进行理论分析,然后结合室内平板荷载试验对理论模型开展验证分析,最后通过室内土箱试验研究,探明了CIPP内衬对既有管道承载能力的提升作用,揭示了复合结构的破坏模式,以及既有管道的椭圆缺陷对CIPP修复效果的影响.研究结果表明:① 自然固化CI…查看全部>>
The cured in place pipe(CIPP)method can be used to rehabilitate high-density polyethylene(HDPE)double-wall corrugated drainpipe,but there is no suitable model to quantitatively evaluate the bearing characteristics of the rehabilitated integral structure,so the rehabilitation design is not based on any evidence.As a result,the theoretical analysis on the overall bearing characteristics of the rehabilitated structure was carried out based on the stacked curved…查看全部>>
