由美国土木工程学会建筑学会的埋地混凝土管箱节直接设计标准委员会编制的ASCE/CI 27-17标准阐述了将使用顶进（一种非开挖施工）安装的预制混凝土管的直接设计。使用顶管技术成功安装管道需要工程师设计安装期间和之后的荷载条件，以及安装承包商的熟练放置和管道的精确制造？本标准涵盖的所有主题。 非开挖施工中顶管用预制混凝土管直接设计的标准实施规程包括用于输送污水、工业废物、雨水和排水的管道，以及用于公用设施和通道的管道。它提出了设计和分析方法，考虑管道和周围土壤和/或灌浆封套之间的相互作用，以确定在顶管过程中产生的纵向荷载，以及管壁中的横向压力分布和周向弯矩、推力和剪力。 包括计算管壁中所需钢筋的程序。附录提供了制造合适管道、管理顶管作业和估算所需顶管力的标准实践。本标准是ASCE 27-00的修订版，可作为编制非开挖装置顶进工程规范的参考，极限状态设计程序与AASHTO公路桥梁标准规范中概述的程序一致。它包括与最新ASTM国际和美国混凝土管协会（ACPA）文件相关的更新。 它将对土木工程设计专业人士、顾问、业主和交通官员有用。

Prepared by theDirect Design of Buried Concrete Pipe Box Sections Standards Committee of the Construction Institute of the American Society of Civil EngineersStandard ASCE/CI 27-17 addresses the direct design of precast concrete pipe that will be installed using jacking, a type of trenchless construction. Successful installation of pipe using jacking techniques requires that the engineer design for loading conditions both during and after installation, as well as skillful placement by the installing contractor and precise fabrication of the pipe?all topics covered in this standard.Standard Practice for Direct Design of Precast Concrete Pipe for Jacking in Trenchless Construction covers piping intended for the conveyance of sewage, industrial wastes, stormwater, and drainage, as well as for utilities and access ways. It presents design and analysis methods that consider the interaction between the pipe and surrounding soil and/or grout envelope in order to determine the longitudinal loads that develop during jacking, as well as transverse pressure distributions and circumferential moment, thrust, and shear in the pipe wall. A procedure for calculating the required reinforcement in the pipe wall is included. Appendixes offer standard practice for manufacturing suitable pipe, managing jacking operations, and estimating the required jacking force.This Standard, a revision of ASCE 27-00, may be used as a reference in preparing project specifications for jacking in trenchless installations, and the limits state design procedure is consistent with the procedures outlined in the AASHTOStandard Specifications for Highway Bridges. It includes updates to correlate with the latest ASTM International and American Concrete Pipe Association (ACPA) documents. It will be useful to civil engineering design professionals, consultants, owners, and transportation officials.
