青岛理工大学毕业论文 摘 要

桩基础广泛用在建筑物特殊地基的处理上，具有极其重要的作用，但是人们对建筑物质量控制上总是出现各种各样的问题，如果建筑物的基础出现质量问题，建筑物就容易出现安全隐患，人们的正常居住安全不能够得到保障。因此，要在经济合理的原则下，对地基和基础的质量提出严格的要求。

《建筑桩基技术规范》中明确指出桩基的设计与施工应综合考虑地质条件上部结构类型荷载特征施工技术条件与环境检测条件等因素精心设计施工，设计施工人员要按照质量要求和技术规范切实严格进行质量控制。本论文根据《建筑桩基技术规范》和《建筑地基基础技术规范规定》的桩基础的施工标准和技术参数，对施工过程中的每一个步骤的质量进行严格控制，对施工过程中出现的质量问题进行系统分析，及时纠正和预防，对工程的质量进行验收，使得工程能够顺利地进行下去。实际工程中人们对建筑物的质量管理只要严格遵守规范和标准，工程质量就能够有效保证。

青岛理工大学毕业论文 Abstract

Pile foundations are widely used in the handling of special buildings, has an extremely important role, but it is always on quality control of buildings, various kinds of problems, if the basis for building quality problems, building easy to a security risk, it's normal residential security can not be guaranteed. Therefore, to the principle of economic rationality, on the basis of the quality of the proposed foundation and stringent requirements.

\of pile foundation should be considered the type of geological conditions, load characteristics of the upper structure construction technology and environmental testing conditions, conditions and other factors carefully design and construction, design and construction staff to the quality requirements and technical specifications in accordance with the effective strict quality control. According to the paper, \Pile technical specifications\and \specification of building foundation\the construction every step of the process of strict quality control, quality of construction occurred during issues of system analysis, and timely corrective and preventive, acceptance of the quality of the project, the project was able to go smoothly. People building the actual project as long as strict quality control norms and standards compliance, quality can effectively guaranteed.

Keywords: Pile foundation,Concrete pile;Precast concrete piles;Quality control
