将波纹钢板桥涵结构简化为单位宽度的固支圆弧梁,同时考虑波纹钢板桥涵结构和土的共同作用,首次建立了该结构的计算模型,推导了该结构位移、应力的解析解.实例计算结果表明:理论计算结果和现场实测结果相当吻合.在此基础上,编制MATLAB程序,进一步分析波纹板厚、波峰高度、波长、结构半径,土体自重、侧压力系数,以及弹性模量对结构位移、应力的影响,为该结构优化设计和施工提供了理论依据.(The simplified structure of corrugated steel culvert unit width clamped circular beam, taking into account the corrugated steel culvert structure and interaction of soil for the first time to establish a computational model of the structure, the structural displacement derived analytical solution of stress. Example calculation the results show that: the theoretical calculations and field measurement results are quite consistent on this basis, the preparation of the MATLAB program, further analysis of corrugated sheet thickness, wave height, wavelength, structure radius, the weight of soil, lateral pressure coefficient, and elastic modulus of the structure. displacement, the impact of stress for the structural optimization design and construction provides a theoretical basis.)

提出了一种求解电磁场有限元 边界元混合法所生成的线性方程组的有效方法 ———内观
法结合多波前法.由于该线性方程组的系数是一个部分稀疏部分满填充的矩阵,为了加速求解,应用内观法将系数矩阵分为 2块,一块是有限元法形成的稀疏矩阵,另一块是边界元法生成的满阵,然后用多波前法求解稀疏矩阵方程,用高斯 约当消去法解满阵方程. 采用该方法,计算了二维多层介质柱体的雷达散射截面.计算结果表明,该方法的计算效率远远高于传统的高斯法.(Proposed for solving mixed finite element boundary element linear equations generated by an effective method of Vipassana--- a combination of multi wave front method. Since the coefficients of linear equations is a part of the sparsely populated part of the full matrix, in order to speed up the solution, application of Vipassana coefficient matrix is divided into two, one is the finite element method for the formation of the sparse matrix, the other is the boundary element method generates the full array, and then use the multifrontal method for solving sparse matrix equation Gauss Jordan elimination method with full matrix equation solution. use this method to calculate the two-dimensional multi-layer dielectric cylinder of the radar cross section. The results show the computational efficiency of this method is much higher than the traditional Gaussian law.)
