摘　　要：在基础设计中有熟悉的文克尔弹性地基模型,在桩水平力计算及支护设计中有m法,如考虑多层土层复杂情况,m法则无法求解,本文将此类问题归入广义m法,利用两结点Hermite单元形函数推导其刚度矩阵。此法便于编制计算机程序,已用于弹性地基梁、桩水平力计算。The Winkle modulus in the design of foundation and the m method in the calculation of pile under horizontal forced and the design of supporting structure are well known but m method is not suitable for the complicated condition of many soil layers. In the paper a generalized m method is presented to deal with the above mentioned condition. Stiffness matrix is formulated by use of Hermite element with two points. The method is convenient to code computer program and has been used to calculate beams on elastic foundation, piles under horizontal forc and supporting structure.
