北京浅山区不均匀建筑地基问题研究

北京浅山区面积较大，地质条件复杂，在工程建设中会经常遇到不均匀地基问题。不同于平原区建筑地基，山区建筑不均匀地基常常涉及基础的稳定性，对地质勘察、岩土设计或施工要求较高，作为一种不良地基现象及问题，若对其认识不清或处理方案设计不合理，常会导致建筑地基基础的变形过大，甚至产生失稳，工程危害性较大。北京浅山区不均匀地基类型较多，在地基处理时须针对场地稳定性、地基承载力及地基处理方案，并结合场地环境地质条件采取适宜的处理措施，以减缓或避免不均匀地基对工程建设的不利影响。本文试对北京浅山区不均匀地基类型、问题进行归纳总结，从勘察、设计、施工及监督等多个方面入手，提出针对性的应对措施，希望能为北京山区工程建设安全提供一些参考和帮助。

STUDY ON THE PROBLEMS OF UNEVEN BUILDING FOUNDATION IN BEIJING SHALLOW MOUNTAIN AREA

Due to larger areas and complex geological conditions in Beijing shallow mountain area, it often encountered uneven foundation problems in project construction. Different from plain buildings foundation, the mountain buildings often involved foundation stability, the requirement for geological investigation and geotechnical design and construction is higher. As a kind of bad phenomenons and problems, if has not Understanding on it, will lead to building deformation and produce instability even destructive. There are more Uneven foundation types in Beijing shallow mountain area, must according to basement stability, bearing capacity and treatment scheme and take appropriate measures combined with the environmental geological conditions in the process of foundation treatment. In order to slow down or avoid the negative impact of the uneven foundation for engineering construction, the paper tries to sum up the types and problems of uneven foundation, from the survey, design, construction and supervision and other aspects, and puts forward the corresponding countermeasures, hoping to provide some references and help for engineering construction safety in Beijing Mountain area and.
