前言 国际预应力协会工程建筑组着手制定一系列建议书,给工程师提供有用的资料。本报告属于其中之一,并已在纽约国际预应力协会1974年第七届会议宣布。 预应力混凝土结构的损坏、加固及病害情况较少,报导更为罕见,所以关于养护专题,目前尚缺乏综合、系统的论述。 在现代工程实践中,工程师们常意外地遇到如何 Preface The International Prestress Association Engineering and Construction Group embarked on a series of proposals to provide engineers with useful information. This report is one of them and was announced at the New York International Prestress Association in 1974 at its seventh session. Prestressed concrete structure damage, reinforcement and disease less, the report is more rare, so the topic of conservation, there is a lack of comprehensive and systematic discussion. In modern engineering practice, engineers often encounter unexpectedly how
