【摘要】 以某地下泵站工程为背景,建立了工程地质体三维数值模型,并根据实际地应力测量结果,基于FLAC3D数值模拟软件,使用应力回归分析方法,对该工程的地应力场进行了反演计算。结果表明:该工程包括厂房及出水阀室的中心区域,在x方向的侧压系数Kx约1.003,而在y方向Ky则约为1.4。计算结果与实测结果基本吻合,说明采用应力回归计算求得的初始地应力场,能够真实的反映工程现场实际情况,其结果具有较好的可靠性,可作为厂房设计、施工和稳定性评价的参考依据。更多还原

【Abstract】 Based on an underground project,a three-dimensional geological model of this project is established.According to the field in-situ stress measurement results,based on FLAC3 D,stress regression analysis method is used to calculate the in-situ stress field of the project.The result shows that:in the project area,the lateral pressure coefficient Kxin the X direction is about 1.003,while Kyin the Y direction is about1.4.The calculated results are in good agreement with the measured ones.It shows that the initial geo-stress field calculated by stress regression can truly reflect the actual situation of the engineering site.The results have good reliability and can be used as a reference for the design,construction and stability evaluation of factory buildings.更多还原
