| 摘 要： | 传统的承压板法变形试验只适合于半无限均匀岩体,不能计算成层岩体中的断层、夹层的弹性模量,必须研究水平成层岩体的分层弹模计算方法,以便分别计算出每一层的弹性参数。为此,利用积分变换求解双调和方程的方法,找到了柔性或固性承压板加压、中心孔法和表面位移法量测位移条件下的解。工程应用证明,方法行之有效,且有常规方法无法替代的优点。

| Abstract: | Traditional bearing plate deformation test is only suitable for semiinfinte homogeneous elastic rock masses. It can't caculate the elastic modulus of faults and seams in layered strata.The method of elastic moduli calculation of divided layer needs to be studied. Hence, integrat transformation was used to solve doubly harmonic equations, and all of the solutions have been found including loading with flexible or rigid bearing plates, under conditions of measured displacement in central borehole or on foundation surface. Engineering applications showed that the methods mentioned above are feasible, effective, and possess irreplaceable merits in comparison with conventional ones. |
