In this paper, a program is made using the 8-nodes isoparametric finite element method to study wave propagation problems ard its interaction with the underground structure of a two-dimensional space-time domain in geo-medium elastic plane strain computer code. When a discontinuity in the derivative of the load with respect to time occurs, in the finite element numerical computations for solving the above-mentioned wave propagation problems, it will generally lead to the so-called initial illness' and 'overshoot phenomenon'. In the finite element analysis for solving wave propagation problems, based on the variational principle and the wave motion theory, this paper analyzes the causes which account for the above occurrence. A method to improve the computational accuracy for numerical solution by considering the acceleration-discontinued characteristics has been given and discussed in detail. Several examples ara compared with theoretical solutions, the computational results are satisfactory.

本文以八节点等参数有限单元法研究了二维时空域岩土介质内弹性平面应变波的传播问题,以及波与地下结构相互作用的动力反应。当荷载对时间的导数有间断时,在求解上述波传播问题的有限元数值计算中将普遍出现所谓的“初始病态”和“超越现象”。本文从变分原理和波动理论出发,对出现以上情况的原因作了分析;提出了考虑加速度间断特性来改进数值解精度的方法。并作了详尽的讨论。若干算例均与理论解作了比较,其结果是满意的。

This paper suggests the method and steps of back analysis calculation utilizing the theory of complex variable function on elastic plane problem. For measured displacements on the model opening of underground powerhouse at Lubuge Hydroelectric Station, the specific calculation has been made. The results of back analysis calculation not only basically accord with the measured data in the site, the calculated results of the finite element and boundary element, but also basically accord with the topography, the dead weight of ovevburden rock mass and the state of geology structure faces. The results of back analysis calculation of different measured section can verify each other. This paper also discusses the influence on the results of back analysis due to the error of fetched value of elasticity constant and the stability study of underground powerhouse.
