对弹性地基梁的计算,1982年作者提出D法,经使用证明,不仅具有杆件有限元法的通用性,而且不用解多元联立、方程式,亦可手算,使计算工作大为简化;另外与通用的差分法与矩阵法计算比较得知:在相同分段数的情况下,有较高精度。多种 For the calculation of elastic foundation beam, in 1982, the author put forward the D method, which proved that it not only has the versatility of the finite element method, but also simplifies the calculation work without solving the multiple simultaneous equations and equations. In addition, compared with the common method of difference method and matrix method, it is known that in the case of the same number of segments, there is higher accuracy. Variety
