弹性地基上梁的计算弹性地基上梁的计算computation of beams on elastic foundationtanxing dilishang Iiangde iisuan弹性地墓上梁的计算(eomputation ofbeams on elastie foundatibn)土建工程中上部结构与地基连接的梁式构件(称为弹性地基上的梁或基础梁)的计甄.水利工程的水闸、船闸等建筑物中，一般都设有基础梁或基础板。基础梁计算的关键在于求解地基反力。它一旦被求出，其余的计算就与普通梁一样。围绕着地基反力的求解，先后提出了下列几种假设。反力直线分布假设假设基础梁与地基之间的压力按直线分布。这就使计算大为简化。但这一假设没有考虑基础梁与地基之间的相对弹性，故计算结果与实际情况不大符合。由于计算简单，在一些小型建筑物的设计中，或在初步设计中，有时还被采用。文克勒假设假设每单位面积上所受的压力与地基沉陷成正比。这一假设可以用于变宽度的基础梁，也可用于任何形状的基础板。但按此假设，沉陷只发生在地基的受压部分。实际上，沉陷也发生在受压范围以外。半无限大弹性体假设假设地基是半无限大理想弹性体，采用弹性力学中半无限大弹性地基的沉陷公式来计算地基的沉陷。显然一般土壤与理想弹性体是有区别的。土壤是颗粒体，而且不能或几乎不能承受拉力。因此，必须土壤中没有拉应力发生时，这个土壤地基才能当做连续体看待。中厚度假设假设地基是中等厚度的弹性层(有限压缩层)，用弹性力学导出地基的沉陷公式。按照后两种假设计算基础梁时，必须把问题区分为平面问题和空间问题，前者又必须区分为平面应力问题和平面形变问题。如果地基是均匀整岩，或是很厚的均匀土层，才能用半无限大弹性体假设来计算。如果可压缩土层的厚度和基础的最大水平尺寸同阶大小，则须按照中厚度地基假设来计算。如果地基的可二庄缩层较薄，与基础的最大水平尺寸相比，成为一个很薄的垫层，那就可以按照文克勒假设来计算。基础梁的计算通常有两种方法:一种是导出基础梁的基本方程(微分方程和积分方程)，然后求解这些方程。在文克勒假设下，基本方程成为四阶线性常系数的微分方程，可以用初参数法求解。用这种解法所得的成果，已编制成许多计算用表，可以查用。另一种是把基础梁和地基之间连续接触变换为连杆联系，把基础梁变换为弹性支座上的连续梁，然后用结构力学中的力法、位移法或混合法进行计算。这种方法称为连杆法。连杆法是将全梁分为几个区段，各区段的长度都是c，并在每一区段的中心安置一根铅直连杆与地基相连，如图，为了组成儿何不变体系，必须再加一根水平连杆，但是它的内力等于零。
