三峡库岸区地下工程抗浮问题是影响目前库区大规模建设必须面临的难题,也是急需解决的技术问题。本文通过三峡库区某滑坡堆积地层抗浮桩试验和测试,分析了各地层中抗浮桩桩身轴力和桩侧阻力的大小及分布,对港口有关规范在类似场地工程的适用性及相关经验参数选取进行了讨论,验证了勘察资料提供相关参数的适宜性,对后期抗浮桩设计提出了建议,为三峡库区受库水水位变化影响的建筑物抗浮设计积累了可参考的资料。
The anti-floating of underground works in the reservoir area of the Three Gorges Reservoir is a difficult problem that must be faced in the present large-scale construction of the reservoir area and also an urgent technical solution to the problem. In this paper, through the test and test of anti-floating piles in a landslide accumulation area in the Three Gorges Reservoir Area, the axial force and pile-side resistance of the anti-floating pile in each stratum are analyzed. The applicability of the relevant norms of port to similar site works and their correlation The selection of empirical parameters was discussed to verify the suitability of the relevant parameters of survey data and to provide some suggestions for the design of anti-floating piles in the late stage. Therefore, reference materials for the anti-floating design of buildings affected by the change of reservoir water level in the Three Gorges Reservoir Area .
