ASCE/CI 27-17 | Standard Practice for Direct Design of Precast Concrete Pipe for Jacking in Trenchless Construction
ASCE/CI 27-17《非开挖施工中顶进用预制混凝土管道直接设计标准规程》,是对ASCE 27-00版本的修订,为非开挖顶进施工场景下预制混凝土管道的直接设计提供统一技术依据,适用于输送污水、工业废水、雨水、排水的管道,以及市政公用设施和通道用管道。规范核心围绕管道设计与施工全流程,明确需同时考虑顶进施工期间与完工后的荷载条件,提供了管道与周边土壤、灌浆层相互作用的设计分析方法,可计算顶进时产生的纵向荷载、管道横向压力分布及管壁环向弯矩、推力与剪力,还包含管壁所需配筋量的计算流程。此外,规范附录涵盖预制混凝土管道制造标准、顶进作业管理指南及顶进力估算方法,其极限状态设计流程与AASHTO公路桥梁标准规范相协调,并更新以适配最新的ASTM国际标准及美国混凝土管道协会(ACPA)文件,是土木工程师、咨询人员、项目业主及交通部门开展非开挖顶进预制混凝土管道设计与项目技术文件编制的核心参考。
