摘要
本文利用阻尼最小二乘法推导了Love面波法反分析成层地基中土的有关参数的公式。文献[1]利用有限元与半无限元相结合的方法已能精确有效地求解成层地基中Love面波的理论弥散曲线。在此基础上,本文给出了利用实测的Love面波的弥散曲线反分析土层参数的方法,并编制了相应的计算机程序。最后,通过计算实例验证了本文方法的可靠性和实用性。
The formulation of back calculating soil parameters of layered soils using Love wave method is developed by using damped least square method. The Love wave dispersion curve in a layered soil can be easily obtained by using combination of finite element and semi-infinite element methods as stated in Ref. [1]-Based on it, the authors present the method of back calculation of soil parameters from the measured Love wave dispersion curve , and its computer program is worked out . The applicability and availability of the method presented are confirmed by numerical examples.
