国家建委针对近年来出现的一些工程质量问题,从一九七二年八月份起,组织了有关单位对自防水屋面渗漏、组合屋架倒塌、地基基础沉陷、山区塌方滑坡四个技术问题作了调查研究,并于一九七二年十一月二十三日至十二月四日在河南省开封市召开了建筑技术座谈会。参加座谈会的有十个省市和六个工业部及其他单位的代表共一百二十七人,各单位向座谈会提出了六十份技术资料。在这次建筑技术座谈会上分别对屋面屋架、地基滑坡两个专题进行了经验交流。代表们列举了近年来勘察、设计、施工、科研方面正反两个方面的经验和教训,用大量的实例说明了工程质量问题是个路线问题。遵照毛主席一贯倡导的理论和实践相结合的原则,总结了几年来推行自防水屋面板和组合屋架的经验教训以及黄土地区和山区建设中遇到的各种地基问
In August of 1972, the National Construction Commission organized relevant units to address four engineering problems that have emerged in recent years, including leakage of waterproof roofs, collapse of composite roof trusses, subsidence of foundations, and landslides in mountainous areas. Investigation and research, and held a forum on construction technology in Kaifeng City, Henan Province, from November 23, 1972 to December 4. A total of 127 representatives from ten provinces, municipalities and six industrial departments and other organizations participated in the forum. Each organization submitted 60 technical materials to the forum. At this forum on construction technology, the two topics of roof trusses and foundation landslides were exchanged. The delegates listed the experiences and lessons of the pros and cons of exploration, design, construction, and scientific research in recent years. It has been illustrated with a large number of examples that the project quality problem is a route issue. In accordance with the principle of combining the theory and practice that Chairman Mao has always advocated, the lessons learned from the implementation of waterproof roofing panels and trussed roof trusses over the past few years and the various ground problems encountered in the construction of loess areas and mountains have been summarized.
