1 问题提出墙下刚性条形基础的两个基本尺寸,即基础底宽B和基础高度H如图1所示,必须满足地基承载力和基础材料的刚性角两个条件。文献据此给出计算墙下条形刚性基础两个基本尺寸的算式:B≥N/fH≥(B-Bo)/(2tgα)问题是:计算两个尺寸时,基础及基础上土重与两个尺寸有关.所以N是未知的。文献所给计算两个尺寸的题中,认为 1 PROBLEMS Two basic dimensions of a rigid strip foundation under a wall are proposed, that is, the foundation bottom width B and foundation height H are shown in Fig. 1, and two conditions of foundation bearing capacity and base material stiffness must be satisfied. The literature gives the formula for calculating two basic dimensions of the rigid foundation of a wall under the wall: B ≧ N / fH ≧ (B-Bo) / (2tgα) The problem is that when calculating two dimensions, Two sizes are relevant, so N is unknown. The literature gives two questions in calculating the size, think
