摘要
初始地应力是岩土工程设计与施工所要考虑的重要因素之一,根据实测地应力资料,采取三维有限元回归分析方法,充分考虑岩体自重与构造应力的影响,利用多元线性回归原理,可得到计算区域的初始地应力场。对某高速公路隧道的地应力回归分析结果表明,计算结果与实测值吻合较好,可作为工程设计与施工的依据。
Initial geostress is one of the most important factors in geotechnical design and construction. According to in situ measurement,with 3D FEM regression analysis used,considering the gravity and con- structional stresses of rock mass,and by using multivariate regression analysis principle,the initial stress field of the calculation area can be obtained. The geostress regression analysis results of a highway tunnel indicate that the calculated results are in a good agreement with the in situ measured data and can be used to engineering practice.
