摘要
PROBLEM TO BE SOLVED: To provide a highly accurate numeric value analyzing method capable of quantitatively incorporating influence of rigidity with respective layers of the improved ground into a settlement/ stress calculation.;SOLUTION: This equivalent elasticity analyzing method is a hybrid method of simultaneously using an equivalent elastic modulus method and an equivalent conversion thickness method as a calculation method on settlement/stress of the improved ground. First of all, the improved ground is constituted of an improved body and the original ground, and is modeled as the equivalent composite ground by using the equivalent elastic modulus method. Next, the composite ground is modeled as the multilayer ground having an equivalent elastic modulus by using a stress dispersion width by the equivalent conversion thickness method. As a result, a solution of a simple closed shape (closed form) applicable to a basic calculation is presented. A loaded width of a vertical load, an improved width of the improved ground, the improved depth and a difference in rigidity between the improved ground and the original ground, clear up influence acting on a dynamic characteristic on instant settlement and vertical stress of the improved ground.;COPYRIGHT: (C)2006,JPO&NCIPI
