摘要
在计算墙下条形基础的宽度时,一般采用公式B=N/(R-D·Y)。由于这种计算方法重复二次计算纵横墙交叉处承载面积,因此计算的结果带有负误差,从而严重地影响了计算精度和结构的安全度。以一个简化的基础平面为例,导出计算误差较小的建议公式,以改进墙下条形基础宽度的计算方法。
Commonly the formula of B=N/(R-D·Y) is used in the calculation of the width of strip foundation. This method calculates the loaded area at the cro ss points of the longitudinal wall and the horizontal wall for two times, so its results have the negative errors, influencing the accuracy of the calculation a nd the safety degree of the structure. Taking a simplified foundation plane as t he example, this paper derives a recommended formula with less calculation error s, improving the method for calculating the width of strip foundation.
