筏形基础的质量控制.doc

摘  要

质量是人类文明程度的标志，建筑工程质量关系人民生命财产安全，关系国家和民族的形象，工程质量责任重于泰山。随着社会主义市场经济的建立，除了经济上的因素外，更重要的是质量和信誉的竟争，质量问题勿须置疑成了头等大事。万丈高楼从地起更加强调了地基基础的重要性，地基基础的质量更关乎建筑物整体结构的质量。本文重点研究建筑地基基础中筏形基础的施工质量控制。地基基础施工质量控制是工程项目全过程质量控制的关键环节，工程质量很大程度上决定于施工阶段质量控制。通过对施工阶段工程项目质量控制的研究，分析影响工程质量的因素，探索质量控制的系统过程、依据程序、控制内容、方法和手段等，运用统计方法进行质量分析和动态控制，以人的工作质量保工序质量，促工程质量，重点强调构建施工现场质量保证体系和施工单位(企业)的质量管理。

Abstract

Quality is the mark of human civilization.So the construction engineering qualityrelates to people's life and property,and image of the nation.The duty of engineeringquality is heavier than the weight of Mountain Tai. With the market economy of the socialism cstab lishing. WTO, since our countryfastens steps of fondational Tacilitices,the inside need will increase,national economy develop healthily and the domestic and international market will further extend. With the foreign building (group)company flowing into the domestic market in 2003,this will produce mighty impact on the local building business enterprises.Through several decades'development, the domestic building (group) business enterprise has some competition, but if they want to connect with the international, match with international building group mutually. The most important thing are the competition of the quality and prestige. This paper's point is researching the quantity control of building enterprise on construction stage. Quality control of stage is key link of construction item of the whole process.The construction quality is decided by construction stage control. Through the research of the stage in construction item quantity control, analyzing the factor that affect the engineering to the quality, investigate the system process of the quality control, according to the procedure, control contents, method and means etc., use of the statistic method to analyxe and control the development, protecting the work quality through the person's work quality, enhancing engineering quality. The key point is to set up the system of quality guarantee on the construction spot and management of construction (business enterprise).

Key word： quality control，Construction stage, engineering item
